The GCF of two even numbers is even.

No, the only way the GCF and LCM of two numbers can be the same is if the numbers are the same.

You don't; you need at least two numbers to find a GCF.

The GCF of two numbers multiplied by their LCM will equal the product of the original numbers. If you know the GCF, divide it into the product of the two. The result will be the LCM. If the GCF of two numbers is 1, the LCM is their product.

For any two natural numbers a and b:Product of a and b = LCM(a,b) x GCF(a,b)Let one of the numbers be y, then other number = (55 - y)So,y(55 - y) = 450 x 555y - y2 = 2250On solving the equation we gety = 5/2(11 Â± i(239)1/2)where i = (-1)1/2Solutions of the given equation are two complex numbers but according to question we need natural numbers. Since GCF and LCM are defined for natural numbers then there exists no value of y for which the given conditions are true.
