What is the least common multiple of 864,624 and 819. Can you please show the steps. I know that they are both divisible by 3 but can't find the next lowest prime number to divide them by?

288,208 * 3 and 273 *3

273 = 3 * 91 but 91 = 7*13
so
819 = 3 * 3 * 7 * 13

well can I divide 288208 by 7 or 13 ?
nope
I do not think there is anything beyond 3
(I bet there is a typo)
