Given numbers are 858, 856, 680, 812

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

Apply this formula for all numbers.

Step1:

LCM(858, 856) = 367224

GCD(858, 856) = ( 858 x 856 ) / 367224

= 858 / 856

= 858

Step2:

LCM(2, 680) = 680

GCD(2, 680) = ( 2 x 680 ) / 680

= 2 / 680

= 2

Step3:

LCM(2, 812) = 812

GCD(2, 812) = ( 2 x 812 ) / 812

= 2 / 812

= 2

So, Greatest Common Divisor of 858, 856, 680, 812 is 2
