Factor them.
2 x 3 x 3 = 18
2 x 3 x 5 = 30
Combine the factors, eliminating duplicates.
2 x 3 x 3 x 5 = 90, the LCM
6x3
The GCF is 3x
54
54.By the way, what does what and mean?
Eighteen times three is equal to 54.
2x^3(x - 3)(x + 3)
24x^5 + 24x^3 = 24x^3(x^2 + 1)
The GCF is 6.
18 x 3 = 54
The GCF is 9.
The GCF is 4.
The GCF is 30.
