Steps to Calculate GCD of 691, 142, 502, 491 using LCM Formula
Given numbers are 691, 142, 502, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 142) = 98122
GCD(691, 142) = ( 691 x 142 ) / 98122
= 691 / 142
= 691
Step2:
LCM(1, 502) = 502
GCD(1, 502) = ( 1 x 502 ) / 502
= 1 / 502
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 691, 142, 502, 491 is 1
