Steps to Calculate GCD of 257, 491, 667, 491 using LCM Formula
Given numbers are 257, 491, 667, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 491) = 126187
GCD(257, 491) = ( 257 x 491 ) / 126187
= 257 / 491
= 257
Step2:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 257, 491, 667, 491 is 1
