Steps to Calculate GCD of 838, 340, 497, 687 using LCM Formula
Given numbers are 838, 340, 497, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(838, 340) = 142460
GCD(838, 340) = ( 838 x 340 ) / 142460
= 838 / 340
= 838
Step2:
LCM(2, 497) = 994
GCD(2, 497) = ( 2 x 497 ) / 994
= 2 / 497
= 2
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 838, 340, 497, 687 is 1
