Given numbers are 805, 306, 249, 971

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 249 are 3 x 83

Prime factors of 971 are 971

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

Given numbers are 805, 306, 249, 971

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

Apply this formula for all numbers.

Step1:

LCM(805, 306) = 246330

GCD(805, 306) = ( 805 x 306 ) / 246330

= 805 / 306

= 805

Step2:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

Step3:

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

= 1 / 971

= 1

So, Greatest Common Divisor of 805, 306, 249, 971 is 1
