3 = 1 x 3 5 = 1 x 5 7 = 1 x 7 GCF = 1
The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
147 = 3 x 7 x 7, 189 = 3 x 3 x 3 x 7 so GCF = 3 x 7 = 21
Any two integers have a gcf. It is also possible for an odd and an even number to have a gcf other than one; for example, the following numbers (shown in factored form) have the gcf 7: 7 x 7 7 x 8 ex. 3 and 6, the GCF is 3 14 and 21 the GCF is 7
21. 42 = 2 x 3 x 7 63 = 32 x 7 105 = 3 x 5 x 7 gcf = 3 x 7 = 21
The GCF is 3.
No. 3n is not a factor of 3n + 7.
3 = 1 x 3 5 = 1 x 5 7 = 1 x 7 GCF = 1
The Greatest Common Factor (GCF) for 3, 7, 8 is 1 3 = 1, 3 7 = 1, 7 8 = 1, 2, 4, 8
The GCF is 3.
The GCF is 1.
The GCF is 7. Factored fully, that's 7(x + 3)(x -3)
The GCF is 1.
The GCF is: 3
147 = 3 x 7 x 7, 189 = 3 x 3 x 3 x 7 so GCF = 3 x 7 = 21
The GCF is 28.
You need at least two numbers to find a GCF. If that's 3 and 15, the GCF is 3.
