Solution
The correct option is A 8
To find the highest step size to reach the two numbers, determine their highest common factor (HCF).
Factors of 16: 1, 2, 4, 8 and 16
Factors of 24: 1, 2, 3, 4, 6, 8, 12 and 24
Common factors of 16 and 24 are 1, 2, 4, and 8.
∴ Highest Common Factor of 24 and 16 is 8.
∴ The highest step size one can take to reach both the steps 24 and 16 is 8.
