Question

find hcf of 2018 and 2021 in edl method​

Answer 1

Answer:

a and b are positive integers such that a=bq +r, then every common divisor of a and b is a common divisor of b and r, and vice-versa.

Since 2020>2018 we apply the division lemma to 2020 and 2018

2020 = 2018*1 + 2

Since 2018>2 we apply the division lemma to 2018 and 2

2018 = 1009*2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this step is 2, the HCF of 2020 and 2018 is 2.
