Steps to Calculate GCD of 821, 687, 311, 543 using LCM Formula
Given numbers are 821, 687, 311, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 687) = 564027
GCD(821, 687) = ( 821 x 687 ) / 564027
= 821 / 687
= 821
Step2:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
Step3:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
So, Greatest Common Divisor of 821, 687, 311, 543 is 1
