Answer:
Greatest length of pieces = 4 inches
Explanation:
We are given the following information in the question:
Length of yellow ribbon = 52 inches
Length of red ribbon = 64 inches
We have to find length of ribbon such that when it is cut into pieces it does not leave any leftover or residual.
One way to do so is we can find the highest common factor(hcf) or the greatest common divisor(gcd) of both the lengths of the ribbon.
To find hcf we use the method of prime factorization:


Common factor = HCF =

Hence, it can be said that if the yellow ribbon and the red ribbon is cut into pieces of 4 inches, they would not leave any leftover.
