GCF of:

Greatest Common Factor of 0.21, 0.9

Given numbers are 0.21,0.9. The highest number of digits after the decimal point in the given case is 2

Thus, in order to get rid of the decimal point we need to multiply them with 100. On doing so, they are as follows

0.21 x 100 = 21

0.9 x 100 = 90

On finding the GCF of 21,90 we get the Greatest Common Factor as 3

GCF of 0.21,0.9 is 0.03

3 21, 90
7, 30

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

Divide the GCF by 100 as we multiplied by it to make the given numbers as integers in the initial step.

By dividing the GCF we get = 3/100 = 0.03

Therefore the Greatest Common Factor of 0.21,0.9 is 0.03
