What is prime factor tree?
Factor trees are a way of expressing the factors of a number, specifically the prime factorization of a number. Each branch in the tree is split into factors. Once the factor at the end of the branch is a prime number, the only two factors are itself and one so the branch stops and we circle the number.
What is the LCM of 80?
The LCM of 80 and 100 is 400. To find the least common multiple of 80 and 100, we need to find the multiples of 80 and 100 (multiples of 80 = 80, 160, 240, 320 . . . . 400; multiples of 100 = 100, 200, 300, 400) and choose the smallest multiple that is exactly divisible by 80 and 100, i.e., 400.
