GCF(3.5, 4.2, 7.7, 9.8) = 0.7

## GCF of 3.5, 4.2, 7.7, 9.8

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 3.5,4.2,7.7,9.8. 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

3.5 x 10 = 35

4.2 x 10 = 42

7.7 x 10 = 77

9.8 x 10 = 98

On finding the GCF of 35,42,77,98 we get the Greatest Common Factor as 7

### Greatest Common Factor (GCF) of 35,42,77,98 By Common Division

 7 35, 42, 77, 98 5, 6, 11, 14

∴ So the GCF of the given numbers is 7 = 7

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 = 7/10 = 0.7

Therefore the Greatest Common Factor of 3.5,4.2,7.7,9.8 is 0.7
