Create factor trees to find the prime factors of the given numbers. Type whole numbers greater than one into the circles that multiply together to give the number in the circle above them. Each branch of the tree will eventually end in a prime number.

Use prime factorization to find the GCF and LCM. Determine whether a given whole number in the range 1-100 is prime or composite. Find common factors and multiples. Find the greatest common factor of two whole numbers less than or equal to 100.
A "Factor Tree" can help: find any factors of the number, then the factors of those numbers, etc, until we can't factor any more. Example: 48 48 = 8 × 6 , so we write down "8" and "6" below 48
Prime factor trees. In order to produce a prime factor tree we need to be able to recall the prime numbers between 1 and 20. These prime numbers are: 2,3,5,7,11,13,17,19 2, 3, 5, 7, 11, 13, 17, 19. Let’s have a look at an example: E.g. Use a factor tree to write 51 as a product prime factors.
20 Φεβ 2021 · Prime factor trees are diagrams that show the prime factorisation of a number. The number is broken down into two of its factors. These factors are then broken down into their factors until only prime numbers remain.
A special diagram where we find the factors of a number, then the factors of those numbers, etc, until we can't factor any more. The ends are all the prime factors of the original number. Here we see the factor tree of 48 which reveals that 48 = 2 × 2 × 2 × 2 × 3. See: Prime Factor.
Prime factor tree method. To do this, list the factors of a number until the number has been reduced to just prime factors. For example, here is the factor tree for the number 2424: You split the original number 2424 into two branches with each factor (6 6 and 44) being written at the end of the branch.
