The GCF is 18.
The GCF is 6.
The GCF is 6.
hcf(12, 36, 42) = 6 12 = 22 x 3 36 = 22 x 32 42 = 2 x 3 x 7 hcf = 2 x 3 = 6
Highest common factor of 36, 42, and 54 is 6.
The GCF is 18.

The GCF is 6.
The GCF is 6.

The GCF of 36, 42, and 54 is 6.
6 (leaving 6 and 7 respectively)
hcf(12, 36, 42) = 6 12 = 22 x 3 36 = 22 x 32 42 = 2 x 3 x 7 hcf = 2 x 3 = 6
The GCF is 2.
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
Highest common factor of 36, 42, and 54 is 6.
18 and 36 do. So do 18 and 54, 36 and 54, 18 and 72, 54 and 72, and an infinite number of other pairs of numbers.
