Do you do a factor rainbow for greatest common factor?
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
How do you find the greatest common factor of 45 using prime factorization?
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.
Find the Greatest Common Factor of 45 and 65?
The Greatest Common Factor of 45, 65 is 5.
What is the greatest common factor of 36 using the towers of the greatest common factor?
It doesn't matter what you use, you still need at least two numbers to find a GCF. If that's 3 and 6, the GCF is 3.
What are common factors of 35 and 48?
First find the greatest common factors. All common factors are also factors of the greatest common factor.The greatest common factor of 48 and 35 is the same as the greatest common factor of 35 and 13 - where 13 is the remainder of the division of 48 by 35 (using Euclid's algorithm).
Can you find greatest common factor of 3 numbers using Euclid's lemma?

How do you find the greatest common factor of 45 using prime factorization?
You do not. To have a greatest common factor, you need two or more numbers. A common factor is a factor that two or more number have in common. However, the prime factorization of all the numbers will help you find the greatest common factor. The greatest common factor will be the prime factors they have in common multiplied together. Example: The prime factors of 45 are 3, 3, and 5. The prime factors of 60 are 2, 2, 3, and 5. The common prime factors are 3 and 5, so the greatest common factor is 3 x 5 = 15.
