Factors of 45: 1 3 5 9 15 45Factors of 63: 1 3 7 9 21 63The GCF of 45 and 63 is 9The GCF is 9.
The GCF of 18 and 27 is 9.
The GCF is 9.
Prime factorization of 18 = 2 x 3 x 3 Prime factorization of 45 = 3 x 3 x 5 Prime factorization of 63 = 3 x 3 x 7 It can be seen that 3 x 3 is the greatest number common in the factorization of 18, 45 and 63. So, GCF is 3 x 3 = 9.
The GCF is 9.
The gcf of 27, 45, 63 and 90 is 18 Hope It Helps:)
The GCF is 9.
9.
The GCF of 63 and 45 = 9
The GCF is 9.
The GCF is 9.
The GCF is 9.
The GCF is 9.
The GCF is 3.
The same as the GCF of 63 and 45 (where 45 is the remainder of the division of 927 by 63).
The GCF is 9.
Factors of 24... 1,2,3,4,6,8,12,24... Factors of 45... 1,3,5,9,15,45... Factors of 63... 1,3,7,9,21,63 - therefore the GCF is 3.
