The common factors of 18 and 36 are 18,9,6,3,2,1.
You need at least two numbers to find a GCF.
Factors for 15: 3, 5 Factors for 36: 2, 3, 4, 6, 9, 12, 18 Highest common Factor: 3
The common factors of 36 and 27 are 1, 3 & 9; the highest common factor is 9.
Since 18 is a factor of 36, all the factors of 18 will be common to 36. 1,2,3,6,9,18
The GCF of 36 and 54 is 18.The factors of 54=1,2,3,6,9,18,27,54The factors of 36=1,2,3,4,6,9,12,18,36GCF: 18The GCF is 18.
The highest common factor of 36 and 63 is 9
The highest common factor of 36 and 90 is 18. Other factors include 9, 6, 3, 2 and 1.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36 The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48 The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
4
It is 12. Beacause the factors of 36 are: 1,36,3,12,4,9,6 and the factors of 84 are: 1,84,7,12 12 is the highest factor that both numbers have in common.
The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. Of these only 1, 2, 3. and 6 are factors of 1218. So 6 is the highest common factor.
