Given numbers are 865, 255, 803

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

Apply this formula for all numbers.

Step1:

LCM(865, 255) = 44115

GCD(865, 255) = ( 865 x 255 ) / 44115

= 865 / 255

= 865

Step2:

LCM(5, 803) = 4015

GCD(5, 803) = ( 5 x 803 ) / 4015

= 5 / 803

= 5

So, Greatest Common Divisor of 865, 255, 803 is 1
