3 x 3 x 5 = 45
2 x 3 x 3 x 3 = 54
3 x 3 = 9, the GCF
918 = 9 x 245 = 9 x 554 = 9 x 6
45 and 54
9, 18, 27, 36, 45, and 54 have a GCF of 9.
The GCF of 10 and 54 is 2.
36 18,2 9,2,2 3,3,2,2 54 27,2 9,3,2 3,3,3,2 2 x 3 x 3 = 18, the GCF
The GCF is 3.
The GCF of 35, 45 and 54 is just 1. There are no common factors between these 3 numbers aside from 1.
9 is the GCF of 45 and 54.
9.Why? Because 9 x 6 = 54, and 9 x 5 = 45. No number larger than 9 is both a factor of 54 AND 45.
The GCF is 9.
The GCF of 45 and 54 is 9. The GCF can't be greater than the difference between the numbers, which is 9 in this case. Since 9 is a factor of both 45 and 54, it is the GCF.
The greatest common factor of 54, 5, 36, and 45 is 1.
the answer is 9
918 = 9 x 245 = 9 x 554 = 9 x 6
9 is the greatest common factor of 18, 45 and 54.
9
Factor both numbers into primes. Circle any common primes and multiply them/ 45=3x3x5 54=2x3x3x3 3x3=9 GCF
