There aren't any common factors, which makes the GCF 1. This is meaningless to factor out, since it leaves the original equation. If you meant to write -5x7, that makes the common factor -x2 and leaves (5x5 + 13)
26
the factor pairs are 1x35, 5x7
the factor pairs are 1x35 & 5x7
the prime factor of 35 is 5x7
The GCF of 26 and 32 is 2. 32=2^5 26=13x2 Note that the only common factor is 2 so it is the gcf.
13x2=26 By Someone?
..........175 ............/\ ..........5x35 ............../\ ............5x7 (remove the dots)
(x - 2)(x + 2)(x - 3)(x + 3)
Since 7 is a factor of 28, it is automatically the GCF.
GCF stands for Greatest Common Factor.
13x2
