Steps to Calculate GCD of 487, 129, 261, 813 using LCM Formula
Given numbers are 487, 129, 261, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 129) = 62823
GCD(487, 129) = ( 487 x 129 ) / 62823
= 487 / 129
= 487
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 487, 129, 261, 813 is 1
