Given numbers are 285, 615, 790, 305

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

Apply this formula for all numbers.

Step1:

LCM(285, 615) = 11685

GCD(285, 615) = ( 285 x 615 ) / 11685

= 285 / 615

= 285

Step2:

LCM(15, 790) = 2370

GCD(15, 790) = ( 15 x 790 ) / 2370

= 15 / 790

= 15

Step3:

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

= 5 / 305

= 5

So, Greatest Common Divisor of 285, 615, 790, 305 is 5
