Given numbers are 638, 961, 955, 339

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

Apply this formula for all numbers.

Step1:

LCM(638, 961) = 613118

GCD(638, 961) = ( 638 x 961 ) / 613118

= 638 / 961

= 638

Step2:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

Step3:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

So, Greatest Common Divisor of 638, 961, 955, 339 is 1
