The GCF is 10.
The greatest common factor of 72 and 47 is 1.
The GCF is 70.
Since 70 is a factor of 700, it is automatically the GCF.
The factors of 39 are:1, 3, 13, 39The factors of 61 are:1, 61The Greatest Common Factor (GCF) is:1

The GCF is 10.
The GCF is 101.
Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
There is 70 & 140 And 70 & 210 And 70 & 280 In fact 70 and any multiple of 70 will have as their greatest common factor 70. Similarly, 140 and any odd multiple of 70 will have the greatest common factor of 70 (eg 140 & 210, 140 & 350) There is not just one pair of numbers with the gcf of 70, but an infinite number of them - take any two relatively prime numbers; multiply them by 70 and the resulting numbers have a gcf of 70 (eg 4 & 9 are relatively prime, so the gcf of 280 (4 x 70) and 630 (9 x 70) is 70; 70 & 101 are relatively prime so 4900 (70 x 70) and 7070 (70 x 101) have a gcf of 70.)
