One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
How do you find the common multiple of 3 and 4?
(i) Multiples of 3 are: 3, 6, 9, 12, 15, 18, 21, 24, …………etc. Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, …………… etc. Therefore, common multiples of 3 and 4 = 12, 24, ………..etc.
How do you find the multiples of two numbers?
Multiples are found by multiplying the number and any integer. Multiply 3 by 1, then by 2, then by 3, and so on. Multiply 5 by 1, then by 2, then by 3, and so on. Look for patterns in the multiples of 5 and in the multiples of 10.
