The GCF of any group of numbers that includes the number 1 is 1.
gcf(15, 42) = 3.
The GCF is: 1
The GCF is 3.
The GCF is 3.
The GCF is 3.
The GCF is 3.
Because 210 is the smallest number that both 30 and 42 divide into equally with no remainder.
The GCF is 15.
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.The common factors are: 1, 2, 3, 6The Greatest Common Factor (GCF) is: 6
The answer is 3
The GCF is 3.
It is: 2
