Steps to Calculate GCD of 685, 291, 694, 811 using LCM Formula
Given numbers are 685, 291, 694, 811
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 291) = 199335
GCD(685, 291) = ( 685 x 291 ) / 199335
= 685 / 291
= 685
Step2:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
Step3:
LCM(1, 811) = 811
GCD(1, 811) = ( 1 x 811 ) / 811
= 1 / 811
= 1
So, Greatest Common Divisor of 685, 291, 694, 811 is 1
