Given numbers are 640, 989, 326, 610

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

Apply this formula for all numbers.

Step1:

LCM(640, 989) = 632960

GCD(640, 989) = ( 640 x 989 ) / 632960

= 640 / 989

= 640

Step2:

LCM(1, 326) = 326

GCD(1, 326) = ( 1 x 326 ) / 326

= 1 / 326

= 1

Step3:

LCM(1, 610) = 610

GCD(1, 610) = ( 1 x 610 ) / 610

= 1 / 610

= 1

So, Greatest Common Divisor of 640, 989, 326, 610 is 1
