Given numbers are 638, 858, 674, 826

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

Apply this formula for all numbers.

Step1:

LCM(638, 858) = 24882

GCD(638, 858) = ( 638 x 858 ) / 24882

= 638 / 858

= 638

Step2:

LCM(22, 674) = 7414

GCD(22, 674) = ( 22 x 674 ) / 7414

= 22 / 674

= 22

Step3:

LCM(2, 826) = 826

GCD(2, 826) = ( 2 x 826 ) / 826

= 2 / 826

= 2

So, Greatest Common Divisor of 638, 858, 674, 826 is 2
