2 ist greatest common factor
The Greatest Common Factor (GCF) is: 1
1 is a factor of every nonzero number, so 42 would have it in common with any other number.
The greatest common factor is the highest number that divides exactly into two or more numbers.32: 1, 2, 4, 8, 16, 3242: 1, 2, 3, 6, 7, 14, 21, 42The GCF of 32 and 42 is 2.The GCF is 2.The GCF is 2.8The GCF is 2.It is: 2
The GCF of 30, 42, and 54 is: 6
There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers.
