It is: 14
You need at least two numbers to find a GCF. If that's 42, 70 and 84, the GCF is 14.
The Least Common Multiple (LCM) for 42 70 84 is 420.The Greatest Common Factor (GCF) for 42 70 84 is 14.
The GCF is 14.
If that's really 4270 and 84, the GCF is 14 and the LCM is 25620. If that's 42, 70 and 84, the GCF is 14 and the LCM is 420.
The GCF is 42.
The GCF of 42 and 84 is 42.
The GCF is 7.7 is the GCF of 42, 49 and 84.
The greatest common factor of the numbers 210 and 84 is 42.
The GCF is 6.
My entry in the contest is: 14 .It's the GCF of 14, 28, 42, 56, 70, 84, and 98.
