Greatest common factor (GCF) of 7.8, 15.6, 16.9 is 1.3.
GCF(7.8, 15.6, 16.9) = 1.3
GCF of 7.8, 15.6, 16.9
Enter two or more decimals separated by "commas"
Ex: 0.2, 0.3 or 0.4, 0.5, 0.6
Given numbers are 7.8,15.6,16.9. 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
7.8 x 10 = 78
15.6 x 10 = 156
16.9 x 10 = 169
On finding the GCF of 78,156,169 we get the Greatest Common Factor as 13
GCF of 7.8,15.6,16.9 is 1.3
| 13 | 78, 156, 169 |
| 6, 12, 13 |
∴ So the GCF of the given numbers is 13 = 13
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 = 13/10 = 1.3
Therefore the Greatest Common Factor of 7.8,15.6,16.9 is 1.3
