Given numbers are 210, 520, 862, 685

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 862 are 2 x 431

Prime factors of 685 are 5 x 137

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 210, 520, 862, 685

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

Apply this formula for all numbers.

Step1:

LCM(210, 520) = 10920

GCD(210, 520) = ( 210 x 520 ) / 10920

= 210 / 520

= 210

Step2:

LCM(10, 862) = 4310

GCD(10, 862) = ( 10 x 862 ) / 4310

= 10 / 862

= 10

Step3:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

So, Greatest Common Divisor of 210, 520, 862, 685 is 1
