Steps to Calculate GCD of 638, 388, 207, 157 using LCM Formula
Given numbers are 638, 388, 207, 157
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 388) = 123772
GCD(638, 388) = ( 638 x 388 ) / 123772
= 638 / 388
= 638
Step2:
LCM(2, 207) = 414
GCD(2, 207) = ( 2 x 207 ) / 414
= 2 / 207
= 2
Step3:
LCM(1, 157) = 157
GCD(1, 157) = ( 1 x 157 ) / 157
= 1 / 157
= 1
So, Greatest Common Divisor of 638, 388, 207, 157 is 1
