What is the greatest common factor of 7 and 8?

1
GCF of 7 and 8 by Listing Common Factors The Greatest Common Factor of 7 and 8 is 1.

How do I find a common denominator?

We can obtain common denominators by multiplying both numerator (top) and denominator (bottom) by the same amount. For example, consider the addition of two fractions that do not have the same denominator: Addition of 2⁄5 and 1⁄2 . First, multiply 2⁄5 by 2⁄2 to get 4⁄10 .

What is the prime factors of denominator of fraction 7 8?

Explanation: As the only prime factor of denominator is 2 , in fact there are three twos ( 2×2×2 ) we can can convert the fraction 78 by multiplying numerator and denominator by 5×5×5 . (This is always possible if only prime factors of denominator are 2 ‘s and 5 ‘s – just multiply by as many 5 ‘s and 2 ‘s).
