GCF requires 2 numbers to compute.
"What do you have in common?" begs the question "In common with what?"
It is the same thing here.◄
15 and any multiple of 15 have a GCF of 15, as do any two multiples of 15 that differ by 15.
16 32 and 48 have a GCF of 16.
15, 30 and 45 is one example.
The GCF is 3.
45, 90 and 135
15 30 45
15 and 30
Factors for 15: 3, 5 Factors for 36: 2, 3, 4, 6, 9, 12, 18 Highest common Factor: 3
The highest common factor of 60 and 75 is 15
Factors of 8 = 1,2,4,8 Factors of 15 = 1,3,5,15 The highest common factor is 1
The only common factor of 36 and 75 is 3.
We want the GCF or highest common factor of 15 and 24. The factors of 15 and 1,3, and 5.For 24 we have 1,3, 8, 12 and 24.Since 5 is not a factor of 24, the GCF or highest factor is 3
15=3*5 27=3*3*3 highest common factor=3
The greatest common factor of the numbers 63 and 15 is 3.
3
3
It is 1 but the highest common factor is 3
The GCF is 3.
The GCF is 3.
The GCF is 3.
Factors for 15: 3, 5 Factors for 36: 2, 3, 4, 6, 9, 12, 18 Highest common Factor: 3
Factors of 15: 1 3 5 15 Factors of 24: 1 2 3 4 6 8 12 24 The highest common factor of 15 and 24 is 3
The only common factor is 3 * * * * * Correction: the only non-trivial factor is 3. Remember that 1 is also a common factor.
The GCF is 3.
