1,2,3,6,9,18
The factors of 16 are: 1, 2, 4, 8, 16The factors of 18 are: 1, 2, 3, 6, 9, 18
The common factors of 16 and 18 are: 1 and 2
The factors of 16 are 1, 2, 4, 8 and 16 the factors of 18 are 1, 2, 3, 6, 9 and 18 2
The common factors are: 1, 2
Since 6 is a factor of 18, all of its factors are common.
The factors of 18 are: 1, 2, 3, 6, 9, 18. The factors of 32 are: 1, 2, 4, 8, 16, 32.
They are all factors of 18, but they are not all the factors of 18. Don't forget the number itself.
Common factors of both numbers are 1 and 2
1 AND 2
The GCF is 2.
The highest common factor (H.C.F) of the numbers 12, 16, and 18 is 2. To find the H.C.F, we can list the factors of each number: the factors of 12 are 1, 2, 3, 4, 6, 12; the factors of 16 are 1, 2, 4, 8, 16; and the factors of 18 are 1, 2, 3, 6, 9, 18. The largest factor common to all three sets is 2.
18, 22, 26 and 30 have two of the same factors as 16.
