Given numbers are 904, 280, 705, 309

The list of prime factors of all numbers are

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

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 705 are 3 x 5 x 47

Prime factors of 309 are 3 x 103

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

Given numbers are 904, 280, 705, 309

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

Apply this formula for all numbers.

Step1:

LCM(904, 280) = 31640

GCD(904, 280) = ( 904 x 280 ) / 31640

= 904 / 280

= 904

Step2:

LCM(8, 705) = 5640

GCD(8, 705) = ( 8 x 705 ) / 5640

= 8 / 705

= 8

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 904, 280, 705, 309 is 1
