Answer:
Definition: (i) factor (ii) multiple. Give five examples of each.
answer:
Factor: The factor of a number is the exact divisor of that number.
Multiple: A multiple of a number is a number obtained by multiplying a natural number.
Example 1: We know 15 = 1 × 15 and 15 = 3 × 5.
∴ 1, 3, 5, 15 are factors of 15.
That is, we can say that 15 is a multiple of 1, 3, 5 and 15.
Example 2: We know that 8 = 8 × 1, 8 = 2 × 4 and 8 = 4 × 2.
∴ 1, 2, 4, 8 are factors of 8.
That is, you can say that 8 is a multiple of 1, 2, 4, and 8.
Example 3: 30 = 30 × 1, 30 = 5 × 6 and 30 = 6 × 5
∴ 1, 5, 6, 30 are factors of 30.
That is, you can say that 30 is a multiple of 1, 5, 6 and 30.
Example 4: 20 = 20 × 1, 20 = 4 × 5 and 20 = 5 × 4
∴ 1, 4, 5, and 20 are factors of 20.
That is, you can say that 20 is a multiple of 1, 4, 5, and 20.
Example 5: 10 = 10 × 1, 10 = 2 × 5 and 10 = 5 × 2
∴ 1, 2, 5, 10 are factors of 10.
That is, you can say that 10 is a multiple of 1, 2, 5, and 10.
