Given numbers are 639, 643, 755, 694

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

Apply this formula for all numbers.

Step1:

LCM(639, 643) = 410877

GCD(639, 643) = ( 639 x 643 ) / 410877

= 639 / 643

= 639

Step2:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 639, 643, 755, 694 is 1
