Given numbers are 640, 652, 904, 338

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

Apply this formula for all numbers.

Step1:

LCM(640, 652) = 104320

GCD(640, 652) = ( 640 x 652 ) / 104320

= 640 / 652

= 640

Step2:

LCM(4, 904) = 904

GCD(4, 904) = ( 4 x 904 ) / 904

= 4 / 904

= 4

Step3:

LCM(4, 338) = 676

GCD(4, 338) = ( 4 x 338 ) / 676

= 4 / 338

= 4

So, Greatest Common Divisor of 640, 652, 904, 338 is 2
