Given numbers are 638, 438, 894, 847

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

Apply this formula for all numbers.

Step1:

LCM(638, 438) = 139722

GCD(638, 438) = ( 638 x 438 ) / 139722

= 638 / 438

= 638

Step2:

LCM(2, 894) = 894

GCD(2, 894) = ( 2 x 894 ) / 894

= 2 / 894

= 2

Step3:

LCM(2, 847) = 1694

GCD(2, 847) = ( 2 x 847 ) / 1694

= 2 / 847

= 2

So, Greatest Common Divisor of 638, 438, 894, 847 is 1
