Given numbers are 806, 877, 404, 420

The list of prime factors of all numbers are

Prime factors of 806 are 2 x 13 x 31

Prime factors of 877 are 877

Prime factors of 404 are 2 x 2 x 101

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 806, 877, 404, 420

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

Apply this formula for all numbers.

Step1:

LCM(806, 877) = 706862

GCD(806, 877) = ( 806 x 877 ) / 706862

= 806 / 877

= 806

Step2:

LCM(1, 404) = 404

GCD(1, 404) = ( 1 x 404 ) / 404

= 1 / 404

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 806, 877, 404, 420 is 1
