You need at least two numbers to find a GCF.
The GCF is 19.
The GCF is: 4
The GCF is 8.
The GCF is 304.
The GCF is 8.
19
The GCF of 304 and 980 is 4.
The GCF is 16.
The GCF of 304 and 475 is 19. This gives you 16 and 25 respectively. You cannot get any more common factors that impact the end figure.
The GCF is 4.
Factors of 133: 1, 7, 19, 133.Factors of 304: 1, 2, 4, 8, 16, 19, 38, 76, 152, 304.GCF (133, 304) = 19
Factor them. 2 x 2 x 2 x 2 x 19 = 304 2 x 2 x 2 x 3 x 37 = 888 Select the common factors. 2 x 2 x 2 = 8, the GCF
