Given numbers are 805, 908, 904, 821

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 908 are 2 x 2 x 227

Prime factors of 904 are 2 x 2 x 2 x 113

Prime factors of 821 are 821

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

Given numbers are 805, 908, 904, 821

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

Apply this formula for all numbers.

Step1:

LCM(805, 908) = 730940

GCD(805, 908) = ( 805 x 908 ) / 730940

= 805 / 908

= 805

Step2:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 805, 908, 904, 821 is 1
