Given numbers are 304, 136, 640, 242

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

Apply this formula for all numbers.

Step1:

LCM(304, 136) = 5168

GCD(304, 136) = ( 304 x 136 ) / 5168

= 304 / 136

= 304

Step2:

LCM(8, 640) = 640

GCD(8, 640) = ( 8 x 640 ) / 640

= 8 / 640

= 8

Step3:

LCM(8, 242) = 968

GCD(8, 242) = ( 8 x 242 ) / 968

= 8 / 242

= 8

So, Greatest Common Divisor of 304, 136, 640, 242 is 2
