The least common multiple, or LCM, is the smallest number that a given set of numbers can be divided into evenly.
Prime numbers can only be divided evenly by one and themselves, for example, 3 can only be divided evenly by 1 and 3, so it is prime. Composite numbers are evenly divisible by at least 3 numbers, such as 4 which is divisible by 1, 2 and 4.
351 is the least common multiple of 39 and 27 since it is the lowest number that can be evenly divided by both.
All of these numbers are composite except for 2, which is prime.Prime numbers are numbers that can only be divided evenly by 1 and itself.Composite numbers can be divided evenly by 1, itself, and at least one more number.
A composite number is a number that has at least 3 factors. (It can be evenly divided by at least 3 number.) 25 has 3 factors: 1, 5, and 25.
72 is the least common multiple of 12, 24, and 36. A least common multiple is the smallest number that two or more numbers can be divided into evenly. Thus, 12 divides into 72 to get an even 6, 24 can be divided into 72 to get 3, and 36 can be divided into 72 to get 2.
The answer would be 60, as it is the lowest number that can be divided evenly by all three numbers.
No, the Least Common Multiple (LCM) for 72 147 is 3,528. The LCM is the lowest number that can be divided evenly by both 72 and 147.
Prime numbers have two factors, composite numbers have more than two.
Prime numbers have two factors, composite numbers have more than two.
Prime numbers have two factors, composite numbers have more than two.
The smallest number that each of the denominators will divide into evenly is called the least common multiple (LCM).
