Given numbers are 639, 649, 529, 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, 649) = 414711

GCD(639, 649) = ( 639 x 649 ) / 414711

= 639 / 649

= 639

Step2:

LCM(1, 529) = 529

GCD(1, 529) = ( 1 x 529 ) / 529

= 1 / 529

= 1

Step3:

LCM(1, 694) = 694

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

= 1 / 694

= 1

So, Greatest Common Divisor of 639, 649, 529, 694 is 1
