Steps to Calculate GCD of 407, 403, 731, 691 using LCM Formula
Given numbers are 407, 403, 731, 691
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(407, 403) = 164021
GCD(407, 403) = ( 407 x 403 ) / 164021
= 407 / 403
= 407
Step2:
LCM(1, 731) = 731
GCD(1, 731) = ( 1 x 731 ) / 731
= 1 / 731
= 1
Step3:
LCM(1, 691) = 691
GCD(1, 691) = ( 1 x 691 ) / 691
= 1 / 691
= 1
So, Greatest Common Divisor of 407, 403, 731, 691 is 1
