What are the common multiples of 3 and 5?
Step 1: List a few multiples of 3 (3, 6, 9, 12, 15, 18, 21, . . . ) and 5 (5, 10, 15, 20, 25, 30, 35, . . . . ) Step 2: The common multiples from the multiples of 3 and 5 are 15, 30, . . . Step 3: The smallest common multiple of 3 and 5 is 15.
What is the least common multiple of 3, 4, and 5?
3 and 5 are already prime, but we should notice that 3,4 and 5 do not have any common factors at all. The LCM must be divisible by all them, so there needs to be a 3, a 4 and a 5. ∴ LCM = 3 × 4 × 5 = 60 The LCM of any numbers is found from their product divided by any common factors to avoid duplicates.
Which is the best calculator for multiples of 3?
