I just have one problem that is driving me nuts, and I'm hoping I'm not missing out on an important rule.

My book says the LCM of 48 and 54 is 432. I keep getting 288 though.

(* = "to the power of")

I factored 48 and got2*3 times 3I factored 54 and got

3*2 times 2.So...unless I'm mistaken, according to the rules I multiply

2*3 times3*2.I keep getting 288.

My apologies in advance if this is a simple computation error, but I just can't get it right.
