Answer 9

In algebra, as in arithmetic, it is frequently desirable to change fractions that have different denominators to equal fractions that have a common denominator.

It is not always easy to discover by inspection the LCD, that is, the least common multiple (LCM) of the given denominators. However, it may be found, as in arithmetic, by factoring the denominators, for it is the product of all their different prime factors, each factor used the greatest number of times that it occurs in any denominator.

This, if the given denominators are \[ax - bx, \], \[a^2 - b^2,\], and \[a^2 - 2ab + b^2\] on factoring we find \[ax - bx = x(a - b)\]; \[a^2 -b^2 - (a+b)(a - b)\]; and \[a^2 - 2ab + b^2 = (a-b)(a-b)\]

Then the factors of the LCD are x, a + b, a - b, and a - b

Therefore the LCD = \[x(a + b)(a - b)^2\]

omg! thank you so much !

Answer 11

If u have a fraction consisting of numbers like 24/62 it will have common factors

U can use the Euclidean Division method to find their highest common factor
