A common
multiple is a number that is a multiple of two or more numbers.
The common multiples of 3 and 4 are 0, 12, 24, ....
The Least Common Multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.
For example, the L.C.M of 3 and 5 is 15 .(see the example above).
The simple method of finding the L.C.M of smaller numbers is to write down the multiples of the larger number until one of them is also a multiple of the smaller number.
Solution: Multiples of 12 are 12, 24...
24 is also a multiple of 8, so the L.C.M of 8 and 12 is 24.
The Least Common Multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.
LOWEST COMMON MULTIPLE (L.C.M.)
The Lowest Common Multiple (L.C.M) is the smallest number that is a common multiple of two or more numbers.For example, the L.C.M of 3 and 5 is 15 .(see the example above).
The simple method of finding the L.C.M of smaller numbers is to write down the multiples of the larger number until one of them is also a multiple of the smaller number.
Example :
Find the Lowest Common Multiple of 8 and 12.Solution: Multiples of 12 are 12, 24...
24 is also a multiple of 8, so the L.C.M of 8 and 12 is 24.
