3 is the answer..
Factor tree of 40: 40 20,2 10,2,2 5,2,2,2
193 is prime. No tree.
Here is a factor tree of eight: 8 / \ 4 2 / \ 2 2
How about: 8*81 = 648 or 2*324 = 648 out of many possibilities
648 x 84x2 4x22x2x 2x 2x2
648 162 4 81 2 2 2 9 9 Equals: 9 squared time 2 cubed.
3 is the answer..
81 is the only such factor.
The least common factor of any set of integers is 1.
No. 780 and above is excellent.
Common factors of 512 and 648 are: 1, 2, 4, and 8.
81 and 3 72 and 12
It is 8(80b+81) when factored
IT IS PRIME there is no factor tree
Factor tree of 204
factor tree of 216
