Steps to Calculate GCD of 638, 437, 354, 761 using LCM Formula
Given numbers are 638, 437, 354, 761
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 437) = 278806
GCD(638, 437) = ( 638 x 437 ) / 278806
= 638 / 437
= 638
Step2:
LCM(1, 354) = 354
GCD(1, 354) = ( 1 x 354 ) / 354
= 1 / 354
= 1
Step3:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
So, Greatest Common Divisor of 638, 437, 354, 761 is 1
