Answer:

StepSince were looking for the common factor of the 18,24,and 36.

first tging to do is to find their factors by finding what numbers can results 18, 24, and 36 when multiplied.

18= 1x18, 2x9, 3x6, 6x3, 9x2, 18x1

thus factors of 18 are

1,2,3,6,9,18

24= 1x24, 2x12, 3x8, 4x6, 6x4, 8x3, 12x2, 24x1

so the factors of 24 are

1,2,3,4,6,8,12,24

36= 1x36, 2x18, 3x12, 4x9, 6x6, 9x4, 12x3, 18x2, 36x1

factors of 36 are

1,2,3,4,6,9,12,18,36

now lets compare them

18= 1,2,3,6,9,18

24=1,2,3,4,6,8,12,24

36=1,2,3,4,6,9,12,18,36

now take away their common factors or factors that can be found in the three given numbers

18= 9, 18

24= 4, 8, 12,24

36= 4, 9, 18,36

those are not common factors of 18, 24, and 36-by-stepexplanation
