Steps to Calculate GCD of 971, 405, 129, 831 using LCM Formula
Given numbers are 971, 405, 129, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(971, 405) = 393255
GCD(971, 405) = ( 971 x 405 ) / 393255
= 971 / 405
= 971
Step2:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 971, 405, 129, 831 is 1
