Given numbers are 640, 397, 833, 808

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

Apply this formula for all numbers.

Step1:

LCM(640, 397) = 254080

GCD(640, 397) = ( 640 x 397 ) / 254080

= 640 / 397

= 640

Step2:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

Step3:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

So, Greatest Common Divisor of 640, 397, 833, 808 is 1
