How to write 30 as a product of prime factors?
We can now use this tree to write 30 as a product of prime factors. Write all of the circled prime numbers found in the prime factor tree as a product. 30 = 2 × 3 × 5
How to write a number as a prime factor?
30 is divisible by 2, so a factor pair for 30 is 2 × 15. Fill in 2 and 15 into the tree. 2 is prime number so we circle this. 15 isn’t prime so we need to extend the factor tree and find a prime factor of it. A factor pair for 15 is 3 × 5. Both 3 and 5 are prime numbers so we circle both of these.
What makes 36 a product of prime factors?
The prime factors of a number are the factors which are also prime numbers. In the case of 36, 2 and 3 are its prime factors. To write 36 as a product of its prime factors, we need a combination of 2 and 3 that we can multiply together to make 36. In this case it’s:
