Given numbers are 255, 287, 403, 757

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

Apply this formula for all numbers.

Step1:

LCM(255, 287) = 73185

GCD(255, 287) = ( 255 x 287 ) / 73185

= 255 / 287

= 255

Step2:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

Step3:

LCM(1, 757) = 757

GCD(1, 757) = ( 1 x 757 ) / 757

= 1 / 757

= 1

So, Greatest Common Divisor of 255, 287, 403, 757 is 1
