Find the HCF of 135 and 165 prime factor method
Numbers 3.5 and 11. The numbers are actually prime factors of 165 (165=3*5*11).
The Greatest Common Factor of 99, 132, 165: 33
165 = 3 x 5 x 11
yes, they are relatively prime.
I used a factor tree. 165 55,3 11,5,3
3 is the smallest prime factor of 165.
It's a prime factor.
3*5*11 = 165
165 55,3 11,5,3
Three
3 x 5 x 11 = 165
No, 144 and 165 are not relatively prime. For them to be relatively prime, the number 1 could be their only common factor, but they also have 3 as a common factor.
The 8 factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165. Of these, 3,5 and 11 are prime.
The greatest common factor of 165 and 180 is 5. The prime factorization of 165 is 11*3*5. The prime factors of 180 are 2*2*5*9.
Prime factor each term then multiply all the common prime numbers together to get the GCF. 42=2x3x7 165=3x5x11 GCF=3
3 x 5 x 11
