Given numbers are 640, 388, 193, 425

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

Apply this formula for all numbers.

Step1:

LCM(640, 388) = 62080

GCD(640, 388) = ( 640 x 388 ) / 62080

= 640 / 388

= 640

Step2:

LCM(4, 193) = 772

GCD(4, 193) = ( 4 x 193 ) / 772

= 4 / 193

= 4

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 640, 388, 193, 425 is 1
