Given numbers are 364, 640, 808, 220

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

Apply this formula for all numbers.

Step1:

LCM(364, 640) = 58240

GCD(364, 640) = ( 364 x 640 ) / 58240

= 364 / 640

= 364

Step2:

LCM(4, 808) = 808

GCD(4, 808) = ( 4 x 808 ) / 808

= 4 / 808

= 4

Step3:

LCM(4, 220) = 220

GCD(4, 220) = ( 4 x 220 ) / 220

= 4 / 220

= 4

So, Greatest Common Divisor of 364, 640, 808, 220 is 4
