Steps to Calculate GCD of 221, 818, 202, 687 using LCM Formula
Given numbers are 221, 818, 202, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 818) = 180778
GCD(221, 818) = ( 221 x 818 ) / 180778
= 221 / 818
= 221
Step2:
LCM(1, 202) = 202
GCD(1, 202) = ( 1 x 202 ) / 202
= 1 / 202
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 221, 818, 202, 687 is 1
