Given numbers are 638, 819, 412, 758

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

Apply this formula for all numbers.

Step1:

LCM(638, 819) = 522522

GCD(638, 819) = ( 638 x 819 ) / 522522

= 638 / 819

= 638

Step2:

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

= 1 / 412

= 1

Step3:

LCM(1, 758) = 758

GCD(1, 758) = ( 1 x 758 ) / 758

= 1 / 758

= 1

So, Greatest Common Divisor of 638, 819, 412, 758 is 1
