Steps to Calculate GCD of 685, 811, 118, 489 using LCM Formula
Given numbers are 685, 811, 118, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 811) = 555535
GCD(685, 811) = ( 685 x 811 ) / 555535
= 685 / 811
= 685
Step2:
LCM(1, 118) = 118
GCD(1, 118) = ( 1 x 118 ) / 118
= 1 / 118
= 1
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 685, 811, 118, 489 is 1
