Given numbers are 821, 216, 806, 802

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 806 are 2 x 13 x 31

Prime factors of 802 are 2 x 401

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

Given numbers are 821, 216, 806, 802

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

Apply this formula for all numbers.

Step1:

LCM(821, 216) = 177336

GCD(821, 216) = ( 821 x 216 ) / 177336

= 821 / 216

= 821

Step2:

LCM(1, 806) = 806

GCD(1, 806) = ( 1 x 806 ) / 806

= 1 / 806

= 1

Step3:

LCM(1, 802) = 802

GCD(1, 802) = ( 1 x 802 ) / 802

= 1 / 802

= 1

So, Greatest Common Divisor of 821, 216, 806, 802 is 1
