13 is a prime so its only factors are 1 and 13. 13 is NOT a factor of 9, so the only common factors of the two numbers is 1.
9 and 13
Common factors of 9 and 18 are: 1, 3, and 9.
Factors of 91: 1, 7, 13, 91Factors of 117: 1, 3, 9, 13, 39, 117GCF (91, 117) = 13
Divide both parts by 9, as they are common factors. That gives you 8 and 13.
9 and 25 do not have any factors in common.
9 and 13
One is the only common factor of 8 9 13 and 15?
The factors of 52 are:1, 2, 4, 13, 26, 52The factors of 117 are:1, 3, 9, 13, 39, 117The common factors are:1, 13
The factors of 52 are:1, 2, 4, 13, 26, 52The factors of 117 are:1, 3, 9, 13, 39, 117The common factors are:1, 13The Greatest Common Factor:GCF = 13
The lowest common multiple of 9 and 13 is the product of the two numbers as they are coprime (they have no common factors). This results in a LCM of 117.
-4 and -9
The GCF is 1.
The factors of 13 are:1, 13The factors of 65 are:1, 5, 13, 65The factors of 117 are:1, 3, 9, 13, 39, 117The common factors are:1, 13The Greatest Common Factor (GCF) is:13
The common factors of 13 and 39 are: 1 and 13
The factors of 13 are 1, 13 The factors of 26 are 1, 2, 13, 26 The common factors of 13 and 26 are 1 and 13. The common factors are: 1, 13
The factors of 65 are:1, 5, 13, 65The factors of 117 are:1, 3, 9, 13, 39, 117The common factor that is great than 10 is: 13
Since 13 is a factor of 39, all of its factors are common.
