45 = 3*3*5. So there are only three primes required (or possible). 1 is NOT a prime.
5,7,11,13,17,19,23,29,31,37,41 and 43
-41
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."
No because prime numbers have only two factors.
break it up. 45 times 4 is 180. break 45 up. 15 times 3. three is prime. break up 15. 3 times 5. three is prime and so is 5.break up 4. 2 times 2.the prime factorization of 180 is 2 to the second power times 3 to the second power times 5.
No because 4 is not a prime number. You would need to find the factors of 4 (2x2). 5, 7, 2 and 2 are prime numbers.
1, 2,3,7
This is false. 3 + 4= 7. But two numbers (besides the number itself and 1) times each ather are never prime. This is how we get prime numbers.
No they are not prime numbers because 4 is composite.
4 is not prime.
idkkkkkkkk its 4 my hw :(((((((
The prime factors of 144 are 2(4) and 3(2)That is, 144 = 2 x 2 (4 times) x 3 x 3, and those numbers are primes.
