Answer 1

Step-by-step explanation:

List the factors of each number.

Factors of 95 : 1, 5, 19, 95

Factors of 52 : 1, 2, 4, 13, 26, 52

2 Find the largest number that is shared by all rows above. This is the GCF.

GCF = 11

Method 2: By Prime Factors

1 List the prime factors of each number.

Prime Factors of 95 : 5, 19

Prime Factors of 52 : 2, 2, 13

2 Find the intersection of these primes.

None

3 There is no prime factor shared by all numbers. Therefore, the GCF is 11.

GCF = 11
