154 = 2 x 7 x 11
3 and 5 are both prime and so the prime factorisations are:3 = 3, and 5 = 5.
441 = 3 x 3 x 7 x 7 OR 32 x 72
List the prime factorisations side by side in ascending order. If any prime factor is on both lists they are not relatively prime. If the two lists are disjoint, the numbers are relatively prime.
there are no prime multiples for 75 the prime factors or 75 are 5, 5, and 3
75 = 3 * 5 * 5
If the prime factors of the first whole number are all different from the prime factors of the second whole number, then the GCF is 1.
The prime factors of 75 are: 3, 5
The prime factors of 75 are: 3 and 5
The prime factors of 75 are 3 and 5. The prime factorization of 75 is 3 x 5 x 5.
factors of 75: 1, 3, 5, 15, 25, & 75 prime factors of 75 : 3, 5 prime factorization of 75: 3 x 5 x 5
As a product of its prime factors: 3*5*5 = 75
