Given numbers are 858, 249, 312, 790

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

Apply this formula for all numbers.

Step1:

LCM(858, 249) = 71214

GCD(858, 249) = ( 858 x 249 ) / 71214

= 858 / 249

= 858

Step2:

LCM(3, 312) = 312

GCD(3, 312) = ( 3 x 312 ) / 312

= 3 / 312

= 3

Step3:

LCM(3, 790) = 2370

GCD(3, 790) = ( 3 x 790 ) / 2370

= 3 / 790

= 3

So, Greatest Common Divisor of 858, 249, 312, 790 is 1
