Given numbers are 836, 638, 729, 664

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(836, 638) = 24244

GCD(836, 638) = ( 836 x 638 ) / 24244

= 836 / 638

= 836

Step2:

LCM(22, 729) = 16038

GCD(22, 729) = ( 22 x 729 ) / 16038

= 22 / 729

= 22

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 836, 638, 729, 664 is 1
