Steps to Calculate GCD of 638, 637, 91, 849 using LCM Formula
Given numbers are 638, 637, 91, 849
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 637) = 406406
GCD(638, 637) = ( 638 x 637 ) / 406406
= 638 / 637
= 638
Step2:
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
= 1 / 91
= 1
Step3:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
So, Greatest Common Divisor of 638, 637, 91, 849 is 1
