The GCF is 1.
The GCF is 1.
The systematic way to get the answer is: 90 = 2*3*3*5 210 = 2*3*5*7 So gcf is 2*3*5 = 30
Factors of 49: 1, 7, 49 Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90 GCF (49, 90) = 1
The GCF is 90.
The GCF of 15 and 90 is 15.
The GCF is 5.
If A is a factor of 90, the GCF is A. If A is a multiple of 90, the GCF is 90. If A is co-prime with 90, the GCF is 1.
90 and 180 have a GCF of 90.
The GCF is 90.
GCF of 90 and 75 is 15.
The GCF is 10.
