## GCF of 5.4, 7.2, 19.8

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

GCF of:

Given numbers are 5.4,7.2,19.8. 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

5.4 x 10 = 54

7.2 x 10 = 72

19.8 x 10 = 198

On finding the GCF of 54,72,198 we get the Greatest Common Factor as 18

### Greatest Common Factor (GCF) of 54,72,198 By Common Division

 2 54, 72, 198 3 27, 36, 99 3 9, 12, 33 3, 4, 11

∴ So the GCF of the given numbers is 2 x 3 x 3 = 18

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 = 18/10 = 1.8

Therefore the Greatest Common Factor of 5.4,7.2,19.8 is 1.8
