Since both numbers are prime numbers, the greatest common factor (GCF) of 59 and 13 is 1.
The GCF is 9.
It is: 1
It is: 9
59 does not form the product of 9 and a positive integer, therefore, 59 is not an integer multiple of 9. 59/9 = 6.5 recurring (that is, 6.5555..)
The GCF is 1.
The factors of 59 are: 1, 59 The factors of 81 are: 1, 3, 9, 27, 81
The GCF is 1.
