Given numbers are 287, 721, 270, 543

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, 270) = 1890

GCD(7, 270) = ( 7 x 270 ) / 1890

= 7 / 270

= 7

Step3:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

So, Greatest Common Divisor of 287, 721, 270, 543 is 1
