  1. Highest Common Factor (HCF) & Lowest Common Multiple (LCM)

The highest common factor (HCF) of two whole numbers is the largest whole number, which is a factor of both.

Example

12 & 15

Factors of 12: 1, 2, 3, 4, 6, 12.

Factors of 15: 1, 3, 5, 15.

  1. What is the greatest number of gift hampers that can be made?
  2. How many boxes of chocolates, bottles of wine and tins of cookies are there in each gift hamper?

The lowest common multiple (LCM) of two whole numbers is the smallest whole number which is a multiple of both.

Example:

12 & 15

Multiples of 12: 12, 24, 36, 48, 60, 72, 84, ….

Multiples of 15: 15, 30, 45, 60, 75, 90, ….

Lowest common multiple: 60

Four traffic lights along a street turn red at regular intervals of 1 minutes, 1 minute 10 seconds, 1 minute 18 seconds and 1 minute 31 seconds respectively. Occasionally all four traffic lights will turn red simultaneously. If all the traffic lights turned red simultaneously at 0830, find the next time when this occurs again.

*A prime number is a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).

  1. Square root / cube root

Finding the square root of a number means finding a number that when multiplied by itself gives you the original number.

For example, 7 x 7 = 49, Hence, the square root of 49 is 7.

When doing square root or cube root of a number, the index MUST be:

    1. Square root → even number
    2. Cube root → multiple of 3
