Given numbers are 422, 485, 704, 820

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 485 are 5 x 97

Prime factors of 704 are 2 x 2 x 2 x 2 x 2 x 2 x 11

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

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

Given numbers are 422, 485, 704, 820

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

Apply this formula for all numbers.

Step1:

LCM(422, 485) = 204670

GCD(422, 485) = ( 422 x 485 ) / 204670

= 422 / 485

= 422

Step2:

LCM(1, 704) = 704

GCD(1, 704) = ( 1 x 704 ) / 704

= 1 / 704

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 422, 485, 704, 820 is 1
