Yes.
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 1050 and 1400 is 4200.
The greatest common multiple is infinite and not very practical. The GCF is 4. The LCM is 60.
Probably the most common use is in adding fractions with different denominators. The least common multiple of the denominators is the least common denominator. Each fraction can be converted to one with the common denominator, and then you can add the fractions by adding their numerators.
Use distribution to find the least or greater common factor
Yes.
No.
you use the lcm (least common multiple).
Use one of the usual methods to get the least common multiple. To get additional multiples, multiply this least common multiple by 0, by 1, by 2, by 3, etc.
Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.

multiples: Least Common Multiple
None. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more whole numbers.
The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.The least common multiple of 1050 and 1400 is 4200.
