Given numbers are 685, 664, 957, 903

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

Apply this formula for all numbers.

Step1:

LCM(685, 664) = 454840

GCD(685, 664) = ( 685 x 664 ) / 454840

= 685 / 664

= 685

Step2:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 685, 664, 957, 903 is 1
