The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 212 are 2 x 2 x 53

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 473 are 11 x 43

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

Given numbers are 821, 212, 486, 473

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

Apply this formula for all numbers.

Step1:

LCM(821, 212) = 174052

GCD(821, 212) = ( 821 x 212 ) / 174052

= 821 / 212

= 821

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

= 1 / 473

= 1

So, Greatest Common Divisor of 821, 212, 486, 473 is 1
