16x2 - 49 = 42x2 - 72 = (4x)2 - 72 = (4x - 7)(4x + 7)
The GCF is 9.
The greatest common factor is 9
Factor each one and use each prime factor the most it was used in any of the numbers. 9=3x3 12=2x2x3 81=3x3x3x3 2x2x3x3x3x3=324
Yes, and this is how. 16 x 2 - 9 16x2=32, 32 - 9 =23, so 23 is your answer! Good Question!
1,2,3,4,6,8,9,12,18,24,36,72 factor of 72 1,3,9,27,and 81 is factor of 81
The greatest common factor of 16 72 and 81 is 1.
The GCF of 36, 72, and 81 is 9.
16x2 - 49 = 42x2 - 72 = (4x)2 - 72 = (4x - 7)(4x + 7)
The word "GREATEST" is a superlative adjective and that means there can be only one.GCF(72, 81) = 9.
The GCF is 9.
9
It is 9
Divide both numbers by 9 (a factor of both 72 and 81) and you get 8/9
The GCF is 9.
The GCF is 9.
