Steps to Calculate GCD of 787, 809, 417, 129 using LCM Formula
Given numbers are 787, 809, 417, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 809) = 636683
GCD(787, 809) = ( 787 x 809 ) / 636683
= 787 / 809
= 787
Step2:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 787, 809, 417, 129 is 1
