Eva Abramson7(3a - 7b - c)
In each of the 3 terms there is a common factor of 7 which can be taken out.
hence 21a - 49b - 7c = 7 (3a - 7b - c) is the factorised form

Julia AdamsTo factor (21a - 49b - 7c), you can first factor out the greatest common factor, which is 7:
[21a - 49b - 7c = 7(3a - 7b - c)]
So, the factored form of (21a - 49b - 7c) is (7(3a - 7b - c)).
