Answer 1: Listing multiplesList the first multiples of each number, 15, 25 and 30.
15: 15, 30, 45, 60, 75, 90, 105, 120, 135, 150
25: 25, 50, 75, 100, 125, 150, 175, 200, 225
30: 30, 60, 90, 120, 150, 180, 210, 240, 270
150 is the lowest common multiple of 15, 25 and 30.
Answer 2: Using prime factors
This is done by taking the number with the most same prime numbers and multiply it.
List the prime factorization of each number.
15: 3 x 5
25: 5 x 5
30, 2 x 3 x 5
30 is the only number with a two so one two is taken.
15 and 30 each have a three so only one three is taken.
25 has two 5's so two fives are taken.
2 * 3 * 5 * 5 = 150
150 is the lowest common multiple of 15, 25, and 30.

What is the LCM of 15 25 30 and 40?
The LCM is 600.
What is the LCM for 25 and 15?
The Least Common Multiple (LCM) for 25 and 15 is the smallest multiple that both numbers share. To find the LCM, you can start by listing the multiples of each number: 25 (25, 50, 75, 100, 125, 150, ...) and 15 (15, 30, 45, 60, 75, 90, ...). The smallest multiple that appears in both lists is 75, so the LCM for 25 and 15 is 75.
The LCM of 15 and 30 is?
The LCM is 30.
What is the LCM of 25 15 3?
The LCM is 75.
What is the LCM of 30?
The Least Common Multiple (LCM) of 30 is 30. The LCM is the smallest multiple that two or more numbers have in common. In the case of 30, it is already the smallest multiple of itself, so the LCM of 30 is 30.
