20: 1, 2, 4, 5, 10, 20 36: 1, 2, 3, 4, 6, 9, 18, 36 The GCF is 4.
The GCF is 9. From C2H5.OH: This is wrong. The GCF is 4 (6 x 4, 10 x 4, 9 x 4)
The GCF of 9 and 20 is 1
GCF(4, 7, 9) = 1.
7/20 + 9/10 = 7/20 + 18/20 = 25/20 = 5/4
The GCF is 4.
20: 1, 2, 4, 5, 10, 20 36: 1, 2, 3, 4, 6, 9, 18, 36 The GCF is 4.
40 - 1, 2, 4, 5, 8, 10, 20, 40 27 - 1, 3, 9, 27 the GCf is just 1
The GCF is 9. From C2H5.OH: This is wrong. The GCF is 4 (6 x 4, 10 x 4, 9 x 4)
The greatest common factor of 20 and 90 is 10.10 x 2 = 2010 x 9 = 90
The GCF is 1.
Factors of 12: 1, 2, 3, 4, 6, 12 Factors of 20: 1, 2, 4, 5, 10, 20 Factors of 45: 1, 3, 5, 9, 15, 45 GCF (12, 20, 45) = 1
Factors of 45 are 1, 3, 5, 9, 15, and 45 Factors of 20 are 1, 2, 4, 5, 10, and 20 The GCF of 45 and 20 is 5
The GCF of 4, 8 and 9 is 1.
The GCF of 4 and 9 is 1
The GCF of 9 and 10 is 1
The GCF for 9 and 40 is 1. The greatest common factor is the highest number that divides exactly into two or more numbers. 9: 1, 3, 9 40: 1, 2, 4, 5, 8, 10, 20, 40 The GCF is 1.
