Question

prime factorisation for the following numbers.
[d] 324
​

Answer 1

Step-by-step explanation:

324 ÷ 2 = 162 - No remainder! 2 is one of the factors!

162 ÷ 2 = 81 - No remainder! 2 is one of the factors!

81 ÷ 2 = 40.5 - There is a remainder. We can't divide by 2 evenly anymore. Let's try the next prime number

81 ÷ 3 = 27 - No remainder! 3 is one of the factors!

27 ÷ 3 = 9 - No remainder! 3 is one of the factors!

9 ÷ 3 = 3 - No remainder! 3 is one of the factors!

3 ÷ 3 = 1 - No remainder! 3 is one of the factors!

Answer 2
