What is the GCF of 35, 56 and 63?
GCF (Greatest Common Factor) of two or more numbers is the largest possible number which divides the given numbers exactly without any remainder.
Answer: GCF of 35, 56 and 63 is 7
Lets see how to find the GCF of 35, 56 and 63
Explanation:
GCF of 35, 56 and 63 will the greatest number that divides 35, 56 and 63 exactly, that is, leaving the remainder 0
We will explain two methods to find the GCF of 35, 56 and 63
Methods to Find GCF of 35, 56 and 63

GCF of 35, 56 and 63 by Listing the Common Factors
The factors of 35, 56 and 63 are shown below:
1 and 7 are the only common factors of 35, 56 and 63
So, GCF of 35, 56 and 63 is 7

GCF of 35, 56 and 63 by Prime Factorization
Represent 35, 56 and 35 as a product of its prime factors.
Prime factorization of 35 is 5 × 7
Prime factorization of 56 is 2 × 2 × 2 × 7
Prime factorization of 63 is 3 × 3 × 7
7 is the only common factor in the prime factorization of 35, 56 and 63
GCF is the product of the factors that are common to each of the given numbers.
Since the common factor is 7, the GCF of 35, 56 and 35 is 7
You can find the GCF in any of the above methods but the solution will be the same.
