How do you find the greatest common factor of 54, 45?

Answer 1

Skylar Adams

54 = 2 * 3 * 9, and 45 = 5 * 9. The greatest common is 9.

List the prime factors for both numbers.
Multiply the factors both have in common; if there are non the GCF is 1.

To find the greatest common factor (GCF) of 54 and 45:

List the prime factors of each number.
- Prime factors of 54: ( 2 \times 3^3 )
- Prime factors of 45: ( 3^2 \times 5 )
Identify the common prime factors and their lowest exponent.
- Common prime factor: ( 3 )
- Lowest exponent: ( 1 )
Multiply the common prime factors together. ( GCF = 3^1 = 3 )

Therefore, the greatest common factor of 54 and 45 is 3.

Nova Allen

To find the greatest common factor (GCF) of 54 and 45, you can use various methods such as prime factorization, listing factors, or using the Euclidean algorithm. One common method is to find the prime factorization of both numbers and then identify the common prime factors along with their lowest powers. Then, multiply these common prime factors together to find the GCF.
