Utilise our handy GCF of Decimals Calculator to find the GCF of 2, 3, 7. Get the detailed steps to calculate the greatest common factor of decimals 2, 3, 7 which is 1.0 in the following sections.

Greatest common factor (GCF) of 2, 3, 7 is **1.0**.

**GCF(2, 3, 7) = 1.0**

Enter two or more decimals separated by "commas"

Ex: 0.2, 0.3 or 0.4, 0.5, 0.6

Given numbers are 2, 3, 7

Find the highest number after the decimal place.

Multiply all decimal numbers by 10

2 x 10 = 20

3 x 10 = 30

7 x 10 = 70

Find the GCF of 20, 30, 70

Get the factors of 20, 30, 70

The factors of 20 are 1, 2, 4, 5, 10, 20

The factors of 30 are 1, 2, 3, 5, 6, 10, 15, 30

The factors of 70 are 1, 2, 5, 7, 10, 14, 35, 70

So, the GCF of 20, 30, 70 is 10.

Divide the GCF by 10 as we multiplied by it to make the given numbers as integers before.

Thus, the GCF of 2, 3, 7 is 1.0
