## GCF of 1.5, 4.5, 9

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 1.5,4.5,9. 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

1.5 x 10 = 15

4.5 x 10 = 45

9 x 10 = 90

On finding the GCF of 15,45,90 we get the Greatest Common Factor as 15

### Greatest Common Factor (GCF) of 15,45,90 By Common Division

 3 15, 45, 90 5 5, 15, 30 1, 3, 6

∴ So the GCF of the given numbers is 3 x 5 = 15

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 = 15/10 = 1.5

Therefore the Greatest Common Factor of 1.5,4.5,9 is 1.5
