Steps to Calculate GCD of 457, 129, 50, 690 using LCM Formula
Given numbers are 457, 129, 50, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(457, 129) = 58953
GCD(457, 129) = ( 457 x 129 ) / 58953
= 457 / 129
= 457
Step2:
LCM(1, 50) = 50
GCD(1, 50) = ( 1 x 50 ) / 50
= 1 / 50
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 457, 129, 50, 690 is 1
