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
873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.
You cannot really make a factor tree for 7 because it is already a prime number.
3*3*3*13
The greatest common factor of 195 and 351 is 39.

351 = 3 * 3 * 3 * 13 "Factor trees" are used when teaching students about factorization, and are meant to be done out by hand. In almost all cases, numbers used in factor tree exercises will only contain the "easy primes" (2, 3, 5) and possibly one other prime. (This only applies to some education curricula, and not to more general problems) When writing out the factor tree, start by removing factors of 2 and 5, as these are the easiest to check for. When none remain, check if their are factors of 3 in the number.
The GCF is 27.

The Greatest Common Factor (GCF) is: 1
Rewrite the term as: 351 / 1000 351 and 1000 don't have the non-one common factor, so this is the simplified fraction!
