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

Apply this formula for all numbers.

Step1:

LCM(639, 351) = 24921

GCD(639, 351) = ( 639 x 351 ) / 24921

= 639 / 351

= 639

Step2:

LCM(9, 63) = 63

GCD(9, 63) = ( 9 x 63 ) / 63

= 9 / 63

= 9

Step3:

LCM(9, 738) = 738

GCD(9, 738) = ( 9 x 738 ) / 738

= 9 / 738

= 9

So, Greatest Common Divisor of 639, 351, 63, 738 is 9
