Given numbers are 210, 782, 686, 370

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

Apply this formula for all numbers.

Step1:

LCM(210, 782) = 82110

GCD(210, 782) = ( 210 x 782 ) / 82110

= 210 / 782

= 210

Step2:

LCM(2, 686) = 686

GCD(2, 686) = ( 2 x 686 ) / 686

= 2 / 686

= 2

Step3:

LCM(2, 370) = 370

GCD(2, 370) = ( 2 x 370 ) / 370

= 2 / 370

= 2

So, Greatest Common Divisor of 210, 782, 686, 370 is 2
