3 and 5
43 and 2
Prime factors of 18 are 2 and 3 Prime factors of 45 are 3 and 5
3 and 5
nine 2 is the 45
Neither of them are prime. 45 is divisible by 5 and 9. 1024 is divisible by 2 and 512.
45 and 64 are not prime numbers because they both have more than two factors
The prime numbers from 1 to 45 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, and 43.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. neither 45 nor 54 are prime.
3 x 3 x 5 = 45 2 x 2 x 2 x 7 = 56 Since 45 and 56 don't have any prime factors in common, the GCF is 1.
The prime numbers from 1 - 45 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, and 43.
Numbers are either prime or they aren't. In this case, 45 is divisible by 3 and 15; sixty-four goes into 2, 4, 8 and 32. The term "relatively prime" compares two numbers and their common factors. If the GCF of the two numbers is 1, then they are "relatively prime."
