Given numbers are 815, 186, 381

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

Apply this formula for all numbers.

Step1:

LCM(815, 186) = 151590

GCD(815, 186) = ( 815 x 186 ) / 151590

= 815 / 186

= 815

Step2:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 815, 186, 381 is 1
