Given numbers are 815, 479, 915, 866

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

Apply this formula for all numbers.

Step1:

LCM(815, 479) = 390385

GCD(815, 479) = ( 815 x 479 ) / 390385

= 815 / 479

= 815

Step2:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

Step3:

LCM(1, 866) = 866

GCD(1, 866) = ( 1 x 866 ) / 866

= 1 / 866

= 1

So, Greatest Common Divisor of 815, 479, 915, 866 is 1
