Given numbers are 247, 858, 388, 786

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

Apply this formula for all numbers.

Step1:

LCM(247, 858) = 16302

GCD(247, 858) = ( 247 x 858 ) / 16302

= 247 / 858

= 247

Step2:

LCM(13, 388) = 5044

GCD(13, 388) = ( 13 x 388 ) / 5044

= 13 / 388

= 13

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 247, 858, 388, 786 is 1
