My sister is in sixth grade and is struggling

GCF = 1

Step-by-step explanation:

for the values 4, 5, 6, 8, 10, 11, 14, 42, 45, 60, 63, 90

Solution by Factorization:

The factors of 4 are: 1, 2, 4

The factors of 5 are: 1, 5

The factors of 6 are: 1, 2, 3, 6

The factors of 8 are: 1, 2, 4, 8

The factors of 10 are: 1, 2, 5, 10

The factors of 11 are: 1, 11

The factors of 14 are: 1, 2, 7, 14

The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 63 are: 1, 3, 7, 9, 21, 63

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Then the greatest common factor is 1.

the answer is c

hope this !
