Given numbers are 815, 451, 380

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

Apply this formula for all numbers.

Step1:

LCM(815, 451) = 367565

GCD(815, 451) = ( 815 x 451 ) / 367565

= 815 / 451

= 815

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 815, 451, 380 is 1
