Since 18w is a factor of 54w2y, it is automatically the GCF.
(81 - m2) = (9 - m)(9 + m)
100 V2 - 25 W2 = (10V + 5W) (10V - 5W)Another way to show it:100 V2 - 25 W2 = 25 (4 V2 - W2) = 25 (2V - W) (2V + W)
81 is the only one.
No, 324 is not a factor of 4. However, 324 is a multiple of 4. 324 = 4 x 81
w2+18w+77 = (w+7)(w+11) when factored
Since 18w is a factor of 54w2y, it is automatically the GCF.
18(w - 1)
You need at least two terms to find a GCF.
The grouping of the factors of w^2 + 30w + 81 (a perfect square) is (w + 27) and (w + 3)3 is a prime factor of 27, 30 and 81 but without two terms to compare, there won't be a GCF (not gfc)
It can be. 81 is a factor of 162.
19 is not a factor of 81. Factors of 81 are 1, 3, 9, 27, and 81
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
Since 81 is not divisible by 7 therefore, 7 is not a factor of 81.
9x9=81. Proving that one of the factor trees for 81 is 9xp.
42/6
Nine is the highest common factor of 81 and 9
