Given numbers are 630, 802, 406, 211

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 802 are 2 x 401

Prime factors of 406 are 2 x 7 x 29

Prime factors of 211 are 211

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

Given numbers are 630, 802, 406, 211

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

Apply this formula for all numbers.

Step1:

LCM(630, 802) = 252630

GCD(630, 802) = ( 630 x 802 ) / 252630

= 630 / 802

= 630

Step2:

LCM(2, 406) = 406

GCD(2, 406) = ( 2 x 406 ) / 406

= 2 / 406

= 2

Step3:

LCM(2, 211) = 422

GCD(2, 211) = ( 2 x 211 ) / 422

= 2 / 211

= 2

So, Greatest Common Divisor of 630, 802, 406, 211 is 1
