GCF of:

Greatest Common Factor of 0.21, 0.4

Given numbers are 0.21,0.4. 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

0.4 x 100 = 40

On finding the GCF of 21,40 we get the Greatest Common Factor as 1

GCF of 0.21,0.4 is 0.01

∴ So GCF of numbers is 1 because of no common factors present between them.

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 = 1/100 = 0.01

Therefore the Greatest Common Factor of 0.21,0.4 is 0.01
