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.
The LCM is 600.
The Least Common Multiple (LCM) of 15, 25, and 30 is 150.
