All factors of a number
NEVER! A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
factor tree
It doesn't matter what factors you select to start a factor tree. The only thing that matters about completing it is that all the factors are prime.
In doing the factor tree, you can start with any two factors of the given number. These factors maybe prime or composite. But the resulting factors in the factor tree should always be prime numbers. It means that you have to continue factoring unless you ended up with all prime factors.
Use a factor tree. 221 13,17 All the factors are prime. 13 x 17 = 221
When the bottom branch consists entirely of prime numbers.
No, as long as all the factors are prime when you're done.
Answer: 13Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 39 are 1, 3, 13, and 39.The factors of 91 are 1, 7, 13, and 91.The factors of 130 are 1, 2, 5, 10, 13, 26, 65, and 130.The common factors are 1 and 13. Therefore, the greatest common factor is 13.
Because 45 is not a factor of 60.
When you can no longer break down factors. when all the numbers at the bottom are prime!
All the factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
