GCF of:

Greatest Common Factor of 1.2, 1.5, 1.8

Given numbers are 1.2,1.5,1.8. The highest number of digits after the decimal point in the given case is 1

Thus, in order to get rid of the decimal point we need to multiply them with 10. On doing so, they are as follows

1.2 x 10 = 12

1.5 x 10 = 15

1.8 x 10 = 18

On finding the GCF of 12,15,18 we get the Greatest Common Factor as 3

GCF of 1.2,1.5,1.8 is 0.3

3 12, 15, 18
4, 5, 6

∴ So the GCF of the given numbers is 3 = 3

Divide the GCF by 10 as we multiplied by it to make the given numbers as integers in the initial step.

By dividing the GCF we get = 3/10 = 0.3

Therefore the Greatest Common Factor of 1.2,1.5,1.8 is 0.3
