Given numbers are 865, 404, 387

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

Apply this formula for all numbers.

Step1:

LCM(865, 404) = 349460

GCD(865, 404) = ( 865 x 404 ) / 349460

= 865 / 404

= 865

Step2:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

So, Greatest Common Divisor of 865, 404, 387 is 1
