Steps to Calculate GCD of 638, 974, 157, 509 using LCM Formula
Given numbers are 638, 974, 157, 509
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 974) = 310706
GCD(638, 974) = ( 638 x 974 ) / 310706
= 638 / 974
= 638
Step2:
LCM(2, 157) = 314
GCD(2, 157) = ( 2 x 157 ) / 314
= 2 / 157
= 2
Step3:
LCM(1, 509) = 509
GCD(1, 509) = ( 1 x 509 ) / 509
= 1 / 509
= 1
So, Greatest Common Divisor of 638, 974, 157, 509 is 1
