It's like a mathematical illusion, Try an experiment, just break any number into its factors, you'll always get the factors in prime no. viz. Factors of 20 will be 2x2x5 Factors of 210 will be 2x3x5x7 now notice on these factors 2,3,5,7 is a prime no. So for making calculation easier, we can break any number into factor or multiple of a prime no. Also for your 2nd question, Break all the numbers in simple and simple form, so if you'll break 2 into, you'll get 2x1 4 into 2, you'll get 2x2 6,then 2x3 8, then 2x2x2 10, then 2x5 12,then 2x2x3 14,then 2x7 Now counts all the 2 which gives 11 times two. That's why he wrote 2 to power 11
@cobratatesmindset1for finding number of factors we just need to multiply all the prime numbers, now 6 can be written as 2×3 means we got one more pair of 2 and 3 similarly we will break down every number and collect all the prime numbers , that's how they got powers
one doubt sir highest power of 12 in 60! is what? is it 4*3 = 12 means i need to consider highest power of 4 which is 28 so highest power of 12 in 60! is "28" am i right sir?
6:00 to 6:16 I didn't understand where 12×7×4×3×2×2 is come ?? Sir if we add powers 2 to the power 11 =12 then next you have to add the power of digit 3 to the power 6 that is 9 then why did you write 7 ×4×...... ???🤔🤔
Sir the preceding video to this was number system 3. I need to confirm whether that was the last video of the topic on prime numbers or is there any other video after that? Thanks in anticipation.
I didn't understand the calculation 12×7×4×3×2×2 , in the very first question in this video. How to calculate that result from the numbers we have taken in prime basis?
Sir you're teaching really great. But i have a doubt sir. In the last question, we are dividing 150 by 2 So 2*75= 150 but 2*37 is not equal to 75. But you have written 37. I don't understand this. Please help me out sir.
@@zainkhan-cq3co you cannot go with the decimals. if you try to divide 75 by 2 your answer will come in decimals. Therefore you need to select the preceding nearest number. which in this case will be 74.
Sir in the last question if we can find power of 8 in 2×4 So if we found factors of 4 we get 48 because factor of 2 is 146 so we can tak only common so 48 Explain am I right or wrong
According to the playlist, the video before this one for the number chapter is missing and I don't think this is the explanation video for factorials, so even that is missing.

6,then 2x3
8, then 2x2x2
10, then 2x5
12,then 2x2x3
14,then 2x7
Now counts all the 2 which gives 11 times two. That's why he wrote 2 to power 11

For "number of factors" @ 5:49 why? Power + 1 ??
Because it the trick we have to add one to the power
That's because we also consider power 0 ( ie. prime no. to the power 0 = 1) so to include 0 we need to add 1.

Sir while finding of factorial of 15
You have taken all prime no. Out
