Question

In the factors tree below, find the value of the missing prime factors X, Y, and Z.

• A. X = 1, Y = 3, Z = 5
• B. X = 3, Y = 5, Z = 2
• C. X = 3, Y = 3, Z = 5

Answer 1

The correct option is C X = 3, Y = 3, Z = 5

Factor tree of 45:

Step 1: Factors of 45 = 3 × 15
15 is not a prime number, so it can be dissociated as the product of 3 and 5

The value of X = 3, Y = 3, Z = 5
