Steps to Calculate GCD of 821, 394, 577, 680 using LCM Formula
Given numbers are 821, 394, 577, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(821, 394) = 323474
GCD(821, 394) = ( 821 x 394 ) / 323474
= 821 / 394
= 821
Step2:
LCM(1, 577) = 577
GCD(1, 577) = ( 1 x 577 ) / 577
= 1 / 577
= 1
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 821, 394, 577, 680 is 1
