Now, '3' is a divisor of N. It means that the numbers which divide '3' (ie, its divisors) will also divide N. Thus, we can say the divisors of '3' will divide N. Similarly, for every divisor d of N, we can say that the divisors of d are also the divisors of N.

WebJan 29, 2015 · If, for example, prime divisors of your number are 2, 2, 2, 3 and 7, then you can take 0, 1, 2 or 3 instances of 'ball 2'. Similarly, you can take 'ball 3' 0 or 1 times and 'ball 7' 0 or 1 times. Now, if you take 'ball 2' twice and 'ball 7' once, you get divisor 2*2*7 = 28.
