Given numbers are 639, 849, 779, 960

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

Apply this formula for all numbers.

Step1:

LCM(639, 849) = 180837

GCD(639, 849) = ( 639 x 849 ) / 180837

= 639 / 849

= 639

Step2:

LCM(3, 779) = 2337

GCD(3, 779) = ( 3 x 779 ) / 2337

= 3 / 779

= 3

Step3:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

So, Greatest Common Divisor of 639, 849, 779, 960 is 1
