10 and 15
15 and 20
20 and 25
They will either be three and any multiple of three or multiples of three that differ by three.
These three numbers are all multiples of 6.Their greatest common factor is 6.
The greatest common factor is three.
Any three.
Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
The greatest common factor for the numbers 3 and 37 is 1.
The greatest common factor of 15 and 18 is three.
The greatest common factor is three.
17 is the greatest common factor - it goes into 17 once, and 51 three times.
The greatest common factor (GCF) for twenty-one and seventy-two is three.
You need at least two numbers to find a GCF. There is no common factor for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
The answer is simply three.
