Given numbers are 640, 990, 458, 328

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

Apply this formula for all numbers.

Step1:

LCM(640, 990) = 63360

GCD(640, 990) = ( 640 x 990 ) / 63360

= 640 / 990

= 640

Step2:

LCM(10, 458) = 2290

GCD(10, 458) = ( 10 x 458 ) / 2290

= 10 / 458

= 10

Step3:

LCM(2, 328) = 328

GCD(2, 328) = ( 2 x 328 ) / 328

= 2 / 328

= 2

So, Greatest Common Divisor of 640, 990, 458, 328 is 2
