63 = 3x3x7
77 = 7x11
The next step is identifying any common factors. The only common prime factor is 7. Therefore the GCF of 63 and 77 is 7.
GCF for 77 and 14 is 7.
The GCF is 21.
The GCF is 11.
The greatest common factor of the numbers 44 and 77 is 11.
The GCF is 63.
The GCF is 7.
The GCF of 35 and 63 is 7.The GCF is 7.The GCF is: 77
The GCF is: 63
The GCF is 77.
