Yes, all the factors of 12 are factors of 24.
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.
All the factors of 45 are 1,5,9, and 45
2mn
The GCF is 2mn.
The GCF is 2mn.
2mn + 4n2 and 5m2 - 7mn
They are 1, 2, 4, m, 2m, 4m, n, 2n, 4n, mn, 2mn and 4mn.
Since 2mn is a factor of 4m2n2, the latter is automatically the GCF.
Since 2mn is a factor of 4m2n2, it is automatically the GCF of this problem.
The GCF is 2mn.
The GCF is 2mn.
The GCF of 44m and 60n is 4.
9m2+ 9mn- 4n2
2mn-4
