Given numbers are 815, 347, 256, 785

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

Apply this formula for all numbers.

Step1:

LCM(815, 347) = 282805

GCD(815, 347) = ( 815 x 347 ) / 282805

= 815 / 347

= 815

Step2:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 815, 347, 256, 785 is 1
