15, 30, 45
The first common multiple of 3 4 5 and 7 is 420.
15 is a multiple of 3. 15 is a multiple of 5. That makes it a common multiple of 3 and 5.
They are: 30, 60 and 90
The least common multiple of 3, 5, and 11 is 165.
3 and 5 are factors of 15. 15 is a common multiple of 3 and 5.
The least common multiple of 3 , 5 , 45 = 45
The least common multiple of 3 , 2 , 5 = 30
The least common multiple of 3 , 5 , 2 = 30
The Least Common Multiple of 5, 15, and 3 is 15.
The least common multiple of 3 , 5 , 4 = 60
45 is the least common multiple of 3, 5 and 9.
The least common multiple of 3 and 5 is 15. This, however is not a multiple of 2 so we must find the next common multiple of 3 and 5. This is 30. Since 30 is also a multiple of 2, 30 is therefore the least common multiple of 3, 5 and 2.
