Given numbers are 820, 858, 506, 291

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 506 are 2 x 11 x 23

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 820, 858, 506, 291

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

Apply this formula for all numbers.

Step1:

LCM(820, 858) = 351780

GCD(820, 858) = ( 820 x 858 ) / 351780

= 820 / 858

= 820

Step2:

LCM(2, 506) = 506

GCD(2, 506) = ( 2 x 506 ) / 506

= 2 / 506

= 2

Step3:

LCM(2, 291) = 582

GCD(2, 291) = ( 2 x 291 ) / 582

= 2 / 291

= 2

So, Greatest Common Divisor of 820, 858, 506, 291 is 1
