Given numbers are 712, 378, 389, 815

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

Apply this formula for all numbers.

Step1:

LCM(712, 378) = 134568

GCD(712, 378) = ( 712 x 378 ) / 134568

= 712 / 378

= 712

Step2:

LCM(2, 389) = 778

GCD(2, 389) = ( 2 x 389 ) / 778

= 2 / 389

= 2

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 712, 378, 389, 815 is 1
