Given numbers are 806, 486, 820, 445

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

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

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 445 are 5 x 89

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

Given numbers are 806, 486, 820, 445

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

Apply this formula for all numbers.

Step1:

LCM(806, 486) = 195858

GCD(806, 486) = ( 806 x 486 ) / 195858

= 806 / 486

= 806

Step2:

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

= 2 / 820

= 2

Step3:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 806, 486, 820, 445 is 1
