hi, on factorising 676 = 2^2 * 13^2 so, we get to prime numbers 2 & 13 for gettig two prime factors, we should take care of that there happens no mixing of these prime no. you can treat 2^2 as A & 13 ^2 as B then , 676 = A * B its clear that only two cases can happen, 1) A =1 , B = 676 2) A = 2^2 , B = 13 ^2 ans ... 2 no. of ways are possible
hi,

so, we get to prime numbers 2 & 13
for gettig two prime factors, we should take care of that there happens no mixing of these prime no.
you can treat 2^2 as A & 13 ^2 as B
then , 676 = A * B
its clear that only two cases can happen,
1) A =1 , B = 676
2) A = 2^2 , B = 13 ^2
ans ... 2 no. of ways are possible
