GCF(4, 7, 9) = 1.
The GCF is "7"... for 63 and 56 7 x 8 = 56 7 x 9 = 63
The GCF is 1.
45 = 3 * 3 * 5 63 = 3 * 3 * 7 126 = 2 * 3 * 3 * 7 Gcf = 3 * 3 = 9 45/9 = 5 63 / 9 = 7 126 / 9 = 14
' 1 ' is the only common factor of those numbers.
The GCF is 1.
GCF(4, 7, 9) = 1.
The GCF is 9.
No. 3n is not a factor of 3n + 7.
7, 5, 9...405.
The GCF is 1.
The GCF of 28 and 63 is 7. This leaves you with 4 and 9 respectively. As there are no more common factors between 4 and 9 aside from 1, the GCF remains 7.
The GCF for 91 63 is 7.
The GCF is "7"... for 63 and 56 7 x 8 = 56 7 x 9 = 63
The GCF is 1.
It's either GCF (Greatest Common Factor) or LCM (Least Common Multiple).GCF of 3 and 9 is 3, but seven only has 1 as a common factor with the other two, so GCF is 1.LCM of 3 & 9 is 9, and LCM of 9 and 7 is 7 x 9, so LCM is 63.
