If the HCF of two numbers is equal to one of the numbers, what can be inferred?

Correct Answer: One number is a multiple of the other.

Step 1: Understand what HCF means. HCF stands for Highest Common Factor, which is the largest number that divides both numbers without leaving a remainder.
Step 2: Consider two numbers, let's call them A and B.
Step 3: If the HCF of A and B is equal to A, it means A is the largest number that can divide both A and B.
Step 4: Since A can divide itself, it also means that B must be a smaller number that can be formed by multiplying A by some whole number.
Step 5: Therefore, B is a multiple of A.
Step 6: Similarly, if the HCF is equal to B, then A must be a multiple of B.

Highest Common Factor (HCF) – The HCF of two numbers is the largest number that divides both of them without leaving a remainder.
Multiples – If one number is a multiple of another, it means that the first number can be expressed as the second number multiplied by an integer.
