The list of prime factors of all numbers are

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 231 are 3 x 7 x 11

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 402 are 2 x 3 x 67

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

Given numbers are 819, 231, 560, 402

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

Apply this formula for all numbers.

Step1:

LCM(819, 231) = 9009

GCD(819, 231) = ( 819 x 231 ) / 9009

= 819 / 231

= 819

Step2:

LCM(21, 560) = 1680

GCD(21, 560) = ( 21 x 560 ) / 1680

= 21 / 560

= 21

Step3:

LCM(7, 402) = 2814

GCD(7, 402) = ( 7 x 402 ) / 2814

= 7 / 402

= 7

So, Greatest Common Divisor of 819, 231, 560, 402 is 1
