Solved Examples on Factors of 18
Some of the solved examples on factors of 18 are mentioned below:
Example 1: Samuel got 18 comic books for the school kids. He gave all the books to 9 kids. How many books did each kid get?
Solution: Number of comic books = 18
Number of students = 9
Total number of comic books received by each kid = 18/9 = 2
Therefore, the total number of comic books received by each kid is 2.
Example 2: Find the common factor of 18 and 24.
Solution: Factors of 18 = 1, 2, 3, 6, 9, and 18
Factors of 24 = 1, 2, 3, 4, 6, 8, 12, and 24
Therefore, the common factors of 18 and 24 are 1, 2, 3, and 6.
Example 3: A girl living in the countryside bought 18 pairs of shoes for the people of her village. She gave all the pairs of shoes to 6 people living in the village. How many pairs of shoes did each one receive?
Solution: Number of pairs of shoes = 18
Number of people who received shoes = 6
The total number of pairs of shoes each person received = 18/6 = 3
Therefore, the total number of pairs of shoes received by each person is 3.
