Given numbers are 639, 966, 739, 355

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

Apply this formula for all numbers.

Step1:

LCM(639, 966) = 205758

GCD(639, 966) = ( 639 x 966 ) / 205758

= 639 / 966

= 639

Step2:

LCM(3, 739) = 2217

GCD(3, 739) = ( 3 x 739 ) / 2217

= 3 / 739

= 3

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 639, 966, 739, 355 is 1
