Given numbers are 805, 378, 498, 909

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 498 are 2 x 3 x 83

Prime factors of 909 are 3 x 3 x 101

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

Given numbers are 805, 378, 498, 909

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

Apply this formula for all numbers.

Step1:

LCM(805, 378) = 43470

GCD(805, 378) = ( 805 x 378 ) / 43470

= 805 / 378

= 805

Step2:

LCM(7, 498) = 3486

GCD(7, 498) = ( 7 x 498 ) / 3486

= 7 / 498

= 7

Step3:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

So, Greatest Common Divisor of 805, 378, 498, 909 is 1
