Given numbers are 210, 845, 820, 122

The list of prime factors of all numbers are

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

Prime factors of 845 are 5 x 13 x 13

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 122 are 2 x 61

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

Given numbers are 210, 845, 820, 122

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

Apply this formula for all numbers.

Step1:

LCM(210, 845) = 35490

GCD(210, 845) = ( 210 x 845 ) / 35490

= 210 / 845

= 210

Step2:

LCM(5, 820) = 820

GCD(5, 820) = ( 5 x 820 ) / 820

= 5 / 820

= 5

Step3:

LCM(5, 122) = 610

GCD(5, 122) = ( 5 x 122 ) / 610

= 5 / 122

= 5

So, Greatest Common Divisor of 210, 845, 820, 122 is 1
