We are given the expression,
54x+81
Here we have to find Greatest Common Factor of 54 and 81
Factors of 54 are 1, 2, 3, 6, 9, 18 and 27.
Factors of 81 are 1, 3, 9, 27 and 81.
Greatest common factor of 54 and 81 is 27.
So we take out 27 common, rewriting the expression
27(2x+3)
Answer: 54x+81 in factored form equals 27(2x+3).
