What are the lowest common multiples of 4 5and 8?
Least Common Multiple (LCM) for 4 5 8 is 40.
What is the three lowest multiples of 5 and 4?
Use the methods you learned to get the least common multiple. Then multiply this result by 2, and by 3, to get the next multiples.
What do you notice about the numbers that are multiples of both 3 and 4?
They are all even and multiples of 12, which is the lowest common multiple of 3 and 4.
What is the lowest number that four and five can go into evenly?
The lowest number that two or more numbers can both go into evenly are known as the least common multiple. The easiest way to find the LCM (least common multiple) of two numbers, such as 4 and 5 is to list the multiples of these numbers. The multiple is the answer (product) of the number multiplied by another number. Example: 4 X 1 = 4, 4 X 2 = 8, 4 X 3 = 12, 4 X 4 = 16, 4 X 5 = 20. The multiples I have listed for 4 are 4, 8, 12, 16 and 20. I stopped listing the multiples when I reached 4 X 5 because the number I am comparing to is 5. I then list the multiples of 5 (5, 10, 15, 20) The least common multiple between 4 and 5 is 20 because it is the first multiple they have in common, which means that 20 is the lowest number that 4 and 5 can go into evenly.
What factors of 25 and 4 are LCM?
All factors of 25 and 4 are lowest common multiples of some numbers. Factors of 25: 1, 5, 25 Factors of 4: 1, 2, 4 eg 25 is lcm of 5 and 25. The only (and thus) lowest common factor of 25 and 4 is 1. Thus the lowest common multiple of 25 and 4 is 100.
