Given numbers are 660, 640, 392, 259

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

Apply this formula for all numbers.

Step1:

LCM(660, 640) = 21120

GCD(660, 640) = ( 660 x 640 ) / 21120

= 660 / 640

= 660

Step2:

LCM(20, 392) = 1960

GCD(20, 392) = ( 20 x 392 ) / 1960

= 20 / 392

= 20

Step3:

LCM(4, 259) = 1036

GCD(4, 259) = ( 4 x 259 ) / 1036

= 4 / 259

= 4

So, Greatest Common Divisor of 660, 640, 392, 259 is 1
