Given numbers are 638, 783, 404, 704

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

Apply this formula for all numbers.

Step1:

LCM(638, 783) = 17226

GCD(638, 783) = ( 638 x 783 ) / 17226

= 638 / 783

= 638

Step2:

LCM(29, 404) = 11716

GCD(29, 404) = ( 29 x 404 ) / 11716

= 29 / 404

= 29

Step3:

LCM(1, 704) = 704

GCD(1, 704) = ( 1 x 704 ) / 704

= 1 / 704

= 1

So, Greatest Common Divisor of 638, 783, 404, 704 is 1
