Divisibility by 3, 4, 6, 9 and 11?!

You'll learn how to quickly check if a number is divisible by 3, 4, 6, 9 and 11. The last one I didn't even know until recently! Also known as how to check if something is a factor, or a multiple, of these numbers.

The GRE and GMAT are two of most used graduate exams for those seeking to study a Masters Degree or Masters in Business Administration (MBA) degree. The Graduate Record Exam and Graduate Management Admissions Test have been taken for over 50 years and are taken by approximately 600,000 and 300,000 people worldwide annually, respectively. These exams are typically taken between the ages of 18-40, by those who have completed, or are about to complete, their Bachelors Degree.

You IQ is probably through the roof. To have that much knowledge, being able to apply and then teach it with such a breeze is insane. You are genius! I truly hope one day you will be a millionaire as a reward for your efforts.

I've seen all of your quant videos and I must say that they're incredible. Makes me sad to know that this one's the last in the playlist. I'll move to the verbal videos next. Really hope you release more quant stuff!

Great tricks - at 2:52 - 3:00 you say that the digits 4, 2, 1, 3, 9 add up to 21. They add up to 19. Either way not a multiple of 9.

3 years later and still cooking, truly awesome. Attempted the last question, almost got but messed up with the max velocity which should be divided by the min time🤭. I've been blessed by your videos; on track to finishing the 5 weeks of quants, thank you!

Can you please do a detailed video of Permutations covering most of the important concepts that are frequently tested? It would mean a lot to me.Loving this didatic content.

Thank You Philip! Great tricks which will do wonders to save time in the exam. Currently its not Binge watch Netflix but its Binge watch "The tested tutor" channel on YT for the GRE prep. Kudos to you for all those helpful playlist of yours 💯

Could you please do a video on concept of divisibility? Question example: if m^3/48, what is the minimum possible value of m?

[ishfaqtakkar]

Very nice. I like your videos. Love from Pakistan.

[ameerkret]

Great job .. can you do one video about finding the Reminder questions

[dhruvsharma]

Hey, Philip, you are the sweetest man on the internet making us go through GRE/GMAT together...thank you for making supremely tough things easy. thanks for your efforts. Just wish i get the magic number 320

[janiceakh]

good stuff! Love the way you elaborate concepts. Could you please consider solving ETS tricky question in your videos

[syedrahmani]

Cool Tricks..Please keep uploading quant videos

[eucenor]

only for this specific type of question, if they ask something as easy as if a number is divisible by another number, might as well divide it in calculator and check. otherwise great trick in finding divisibility, helpful in other questions

[ameerkret]

I would ask your help if possible to do one video about Sequences and series 🙏🏻

[nanaodehyee]

I really enjoy your videos Philip. But did you say we can tell people about this trick in parties?😂😂😂

[selvakumarmunusamy]

Suppose, if the last two digits are 00, then how can I conclude the number is divisible by 4 [eg: 100 is divisible by 4 but not 300]?

[thetmonaye]

hi, can we use the calculator ? we divide that given number with x (eg. x = 2 or 3 or 66), if it has decimals, it is not divisible by that number" x "

[timtim]

Very confused with the concept of remainder and divisibility.eg question if m^3 is divisible by 16 then what is the remainder when 4m/16, where m>1. Please help

[tanujababu]

sir, you mentioned the digits to be multiple of 3 and divisible by 2 if the sum is even. At 12:24 the sum of the digits is 21, which is a multiple of 3 but it is not even right?

[Pk_Ige]

what happens with the divisibility by 11 when you get a 0?
