Greatest Common Factor of 4.5, 7.5, 9, 12.3

Handy GCF of Decimals Calculator to know the GCF of decimals 4.5, 7.5, 9, 12.3 i.e. 0.3 the largest integer that divides all the numbers leaving a remainder zero.

Greatest common factor (GCF) of 4.5, 7.5, 9, 12.3 is 0.3.

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
