If x is the multiple of y then LCM of x and y is x. Here, 80 is the multiple of 10 therefore LCM of 10 & 80 is 80.
If the GCF of w and Y is 1, multiply them together.
Their product.
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 4 and 42 is 84.
Y
The least common multiple of two primes x and y, is x * y.
18x2y
That would depend on what integer Y stands for.
