Given numbers are 983, 838, 664, 640

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

Apply this formula for all numbers.

Step1:

LCM(983, 838) = 823754

GCD(983, 838) = ( 983 x 838 ) / 823754

= 983 / 838

= 983

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 983, 838, 664, 640 is 1
