Given numbers are 810, 882, 356, 821

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

Prime factors of 356 are 2 x 2 x 89

Prime factors of 821 are 821

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

Given numbers are 810, 882, 356, 821

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

Apply this formula for all numbers.

Step1:

LCM(810, 882) = 39690

GCD(810, 882) = ( 810 x 882 ) / 39690

= 810 / 882

= 810

Step2:

LCM(18, 356) = 3204

GCD(18, 356) = ( 18 x 356 ) / 3204

= 18 / 356

= 18

Step3:

LCM(2, 821) = 1642

GCD(2, 821) = ( 2 x 821 ) / 1642

= 2 / 821

= 2

So, Greatest Common Divisor of 810, 882, 356, 821 is 1
