Question

The product of three different positive whole numbers is 48.

What is the smallest possible sum of the three different numbers?

Worked Solution

Testing possible combinations:

48 = 24 × 2 × 1, sum = 27

48 = 12 × 4 × 1, sum = 17

48 = 8 × 6 × 1, sum = 15

48 = 8 × 3 × 2, sum = 13

48 = 6 × 4 × 2, sum = 12

∴\therefore The smallest possible sum is 12, made up of 6, 4 and 2.

Question

The product of three different positive whole numbers is 60.

What is smallest possible sum of the three different numbers?

Worked Solution

Testing some possible combinations:

60 = 30 × 2 × 1, sum = 33

60 = 10 × 3 × 2, sum = 15

60 = 6 × 5 × 2, sum = 13

60 = 5 × 4 × 3, sum = 12

∴\therefore The smallest possible numbers are 5, 4 and 3, with a sum of 12.

Question

The product of three different positive whole numbers is 56.

What is smallest possible sum of the three different numbers?

Worked Solution

Testing some possible combinations:

56 = 28 × 2 × 1, sum = 31

56 = 14 × 4 × 1, sum = 19

56 = 8 × 7 × 1, sum = 16

56 = 7 × 4 × 2, sum = 13

∴\therefore The smallest possible numbers are 7, 4 and 2, with a sum of 13.
