Given numbers are 638, 396, 792, 858

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

Apply this formula for all numbers.

Step1:

LCM(638, 396) = 11484

GCD(638, 396) = ( 638 x 396 ) / 11484

= 638 / 396

= 638

Step2:

LCM(22, 792) = 792

GCD(22, 792) = ( 22 x 792 ) / 792

= 22 / 792

= 22

Step3:

LCM(22, 858) = 858

GCD(22, 858) = ( 22 x 858 ) / 858

= 22 / 858

= 22

So, Greatest Common Divisor of 638, 396, 792, 858 is 22
