That would depend on the value of Y.
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 of 14 and 27 is 378
Y
The least common multiple of two primes x and y, is x * y.
18x2y
That would depend on the value of Y.
That would depend on what integer Y stands for.
72xy
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.
That depends on their numerical values.
84x3y
That's known as the least common multiple, or LCM.
