The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 842 are 2 x 421

Prime factors of 921 are 3 x 307

Prime factors of 813 are 3 x 271

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

Given numbers are 402, 842, 921, 813

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

Apply this formula for all numbers.

Step1:

LCM(402, 842) = 169242

GCD(402, 842) = ( 402 x 842 ) / 169242

= 402 / 842

= 402

Step2:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 402, 842, 921, 813 is 1
