Given numbers are 581, 287, 855, 903

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

Apply this formula for all numbers.

Step1:

LCM(581, 287) = 23821

GCD(581, 287) = ( 581 x 287 ) / 23821

= 581 / 287

= 581

Step2:

LCM(7, 855) = 5985

GCD(7, 855) = ( 7 x 855 ) / 5985

= 7 / 855

= 7

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 581, 287, 855, 903 is 1
