Given numbers are 805, 160, 945, 391

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 391 are 17 x 23

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

Given numbers are 805, 160, 945, 391

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

Apply this formula for all numbers.

Step1:

LCM(805, 160) = 25760

GCD(805, 160) = ( 805 x 160 ) / 25760

= 805 / 160

= 805

Step2:

LCM(5, 945) = 945

GCD(5, 945) = ( 5 x 945 ) / 945

= 5 / 945

= 5

Step3:

LCM(5, 391) = 1955

GCD(5, 391) = ( 5 x 391 ) / 1955

= 5 / 391

= 5

So, Greatest Common Divisor of 805, 160, 945, 391 is 1
