What is Euclid’s division lemma?
To find the HCF of two numbers, we generally write them as a product of their prime factors. Then the product of all the common factors is the HCF. However, it may not be easy to apply the prime factorization method if the numbers are large. In such cases, we use the Euclid’s division lemma.

 

Euclid’s division lemma:
Given a dividend and a divisor, there will be a unique pair of quotient and remainder, satisfying the equation
Dividend = Divisor x Quotient + Remainder
This is true for any two positive integers and is referred to as Euclid’s Division Lemma. It states that:
Given positive integers m and n, there exist two unique integers q and r, satisfying m = nq + r, where 0 ≤ r < n.
This lemma is useful to find the HCF of large numbers when breaking them into factors is difficult.
