The GCF is #4#.

The greatest common factor (GCF) is the biggest number that divides evenly into all three numbers.

Sometimes it helps to list the factors of each number.

Factors of #4#: #color(white)(aaa)1, color(red)4#

Factors of #12#: #color(white)(aa)1, 2, 3, color(red)4, 6, 12#

Factors of #24#: #color(white)(aa)1, 2, 3, color(red)4, 6, 8, 12, 24#

The greatest (biggest) factor that is common to (appears in all three lists of factors) of #4, 12 and #24 is #color(red)4#.
