Common factors of 9 and 18 are: 1, 3 and 9. Factors of 9: 1, 3, 9 Factors of 18: 1, 2, 3, 6, 9, 18
The factors of 1 are:1The factors of 3 are:1, 3The factors of 9 are:1, 3, 9The common factor is:1
The factors of 9 are: 1, 3, 9 The factors of 14 are: 1, 2, 7, 14
The factors of 9 are: 1, 3, 9 The factors of 63 are: 1, 3, 7, 9, 21, 63
The factors of 9 are: 1, 3, 9The factors of 18 are: 1, 2, 3, 6, 9, 18The common factors are: 1, 3, 9
4 and 9 are two composite numbers that each have only one other factor besides 1 and themselves. The factors of 4 are 1, 2, and 4, and the factors of 9 are 1, 3, and 9.
A composite number is a number that has additional factors besides ' 1 ' and itself. The number ' 1 ' has no additional factors besides ' 1 ' and itself. So it's not a composite number.
The only common factor and therefore the GCF is 1.
The factors of 27 are: 1, 3, 9, 27 The factors of 45 are: 1, 3, 5, 9, 15, 45 The factors of 81 are: 1, 3, 9, 27, 81
The factors of 9 are 1, 3, and 9
The only factors of 27 besides 1 and 27 are 3 and 9. So the factor pairs are 1 x 27 and 3 x 9.
