GCF(4.5, 7.5, 9, 12.3) = 0.3

## GCF of 4.5, 7.5, 9, 12.3

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 4.5,7.5,9,12.3. 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

4.5 x 10 = 45

7.5 x 10 = 75

9 x 10 = 90

12.3 x 10 = 123

On finding the GCF of 45,75,90,123 we get the Greatest Common Factor as 3

### Greatest Common Factor (GCF) of 45,75,90,123 By Common Division

 3 45, 75, 90, 123 15, 25, 30, 41

∴ 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 4.5,7.5,9,12.3 is 0.3
