Given numbers are 638, 616, 791, 511

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

Apply this formula for all numbers.

Step1:

LCM(638, 616) = 17864

GCD(638, 616) = ( 638 x 616 ) / 17864

= 638 / 616

= 638

Step2:

LCM(22, 791) = 17402

GCD(22, 791) = ( 22 x 791 ) / 17402

= 22 / 791

= 22

Step3:

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

= 1 / 511

= 1

So, Greatest Common Divisor of 638, 616, 791, 511 is 1
