Factor tree of 40: 40 20,2 10,2,2 5,2,2,2
The factors of 37 are 1 and 37. The factors of 81 are 1, 3, 9, 27, and 81. They have only one factor in common - 1. Since the greatest common factor of 37 and 81 is 1, they are relatively prime. You can also look at the prime factors to determine the greatest common factor. 37 is a prime number, so its only prime factor is itself, 37. The prime factors of 81 are 3, 3, 3, and 3. They have no prime factors in common, so they are relatively prime, which means their greatest common factor is 1.
Here is a factor tree of eight: 8 / \ 4 2 / \ 2 2
It's a prime therefore the answer is itself and 1.
873 x 29Since both 3 and 29 are prime numbers, the factor tree is complete.
37 is already prime. No need for a tree.
37 is already prime. No need for a tree.
37 2,
37 is a prime number so its factors are 37 and 1
it is a prime number because no number can go in to 37 but it self.
370 10, 37 2, 5, 37 Note: 37 is a prime number
37 is already prime. It doesn't have a tree. if it did, it would be one branch.
222 2, 111 2, 3, 37
777 = 3 x 7 x 37
If the number on the top layer of the factor tree is 74, the numbers on the second layer are 2 and 37. There are no further layers to the tree, as both factors are prime.
As a product of its prime factors: 3*11*37 = 1221
As a product of its prime factors: 2*3*3*37 = 666
