2 x 2 x 5 = 20 The LCM is 20wy.
Suppose a fraction is written, not in its simplest form, as a/b. Suppose the gcf of a and b is c. Then since c is a common factor of a abd b, a = c*x and b = c*y for some x and y, and since c is the greatest such factor, x and y have no common factor. So a/b = cx/cy = x/y and the latter is the simplest form.
2 * 7 * x * x * y
There is. It's the town with the shortest name in France. People from Y are called Ypsiloniennes (woman) and Ypsiloniens (men). Y not?
y=2x2+5. Plug in 0 for x, and you get y=2(0)^2 +5 =0+5=5. 5 is the minimum value for y.
That depends on their numerical values.
If the GCF of w and Y is 1, multiply them together.
The least common multiple of two primes x and y, is x * y.
That would depend on the value of Y.
That would depend on what integer Y stands for.
The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
