Given numbers are 412, 858, 391, 815

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

Apply this formula for all numbers.

Step1:

LCM(412, 858) = 176748

GCD(412, 858) = ( 412 x 858 ) / 176748

= 412 / 858

= 412

Step2:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 412, 858, 391, 815 is 1
