Given numbers are 805, 731, 147, 520

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 731 are 17 x 43

Prime factors of 147 are 3 x 7 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 805, 731, 147, 520

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

Apply this formula for all numbers.

Step1:

LCM(805, 731) = 588455

GCD(805, 731) = ( 805 x 731 ) / 588455

= 805 / 731

= 805

Step2:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 805, 731, 147, 520 is 1
