List the denominators in a row, sorted left to right, then break each number down to its prime values by dividing by 2, carrying down any numbers that cannot divide evenly. Once you have used 2 for dividing you will have to use the next prime number which is 3. Multiply the prime numbers (2 × 2 × 3)times the denominators (2 × 1 × 1 × 1)equals 24.
2 / 8 4 3 6
2 / 4 2 3 3
3 / 2 1 3 3
2 1 1 1 Take 2 × 2 × 3 × 2 × 1 × 1 × 1 = 24
