Given numbers are 785, 210, 82, 420

The list of prime factors of all numbers are

Prime factors of 785 are 5 x 157

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

Prime factors of 82 are 2 x 41

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 785, 210, 82, 420

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

Apply this formula for all numbers.

Step1:

LCM(785, 210) = 32970

GCD(785, 210) = ( 785 x 210 ) / 32970

= 785 / 210

= 785

Step2:

LCM(5, 82) = 410

GCD(5, 82) = ( 5 x 82 ) / 410

= 5 / 82

= 5

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 785, 210, 82, 420 is 1
