Find the Prime Factorization 165
Problem
Solution
Check for divisibility by the smallest prime number,
2 Since165 is odd, it is not divisible by2 Check for divisibility by the next prime number,
3 The sum of the digits is1 + 6 + 5 = 12.S*i*n*c*e 2i*s(d(i))*v*i*s(i)*b*l*e*b*y , 65i*s(d(i))*v*i*s(i)*b*l*e*b*y $.Divide
165 by3 to find the next factor.
Check for divisibility of
55 by3 The sum of the digits is5 + 5 = 10,w*h*i*c*h*i*s(n)*o*t*d(i)*v*i*s(i)*b*l*e*b*y $.Check for divisibility by the next prime number,
5 Since55 ends in5 it is divisible by5 Divide
55 by5 to find the next factor.
Identify the remaining factor. Since
11 is a prime number, the factorization process is complete.
