Given numbers are 287, 721, 310, 503

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

Apply this formula for all numbers.

Step1:

LCM(287, 721) = 29561

GCD(287, 721) = ( 287 x 721 ) / 29561

= 287 / 721

= 287

Step2:

LCM(7, 310) = 2170

GCD(7, 310) = ( 7 x 310 ) / 2170

= 7 / 310

= 7

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 287, 721, 310, 503 is 1
