Given numbers are 815, 153, 903

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

Apply this formula for all numbers.

Step1:

LCM(815, 153) = 124695

GCD(815, 153) = ( 815 x 153 ) / 124695

= 815 / 153

= 815

Step2:

LCM(1, 903) = 903

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

= 1 / 903

= 1

So, Greatest Common Divisor of 815, 153, 903 is 1
