Given numbers are 823, 620, 800, 291

The list of prime factors of all numbers are

Prime factors of 823 are 823

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 291 are 3 x 97

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

Given numbers are 823, 620, 800, 291

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

Apply this formula for all numbers.

Step1:

LCM(823, 620) = 510260

GCD(823, 620) = ( 823 x 620 ) / 510260

= 823 / 620

= 823

Step2:

LCM(1, 800) = 800

GCD(1, 800) = ( 1 x 800 ) / 800

= 1 / 800

= 1

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 823, 620, 800, 291 is 1
