Given numbers are 570, 828, 409, 805

The list of prime factors of all numbers are

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 409 are 409

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 570, 828, 409, 805

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

Apply this formula for all numbers.

Step1:

LCM(570, 828) = 78660

GCD(570, 828) = ( 570 x 828 ) / 78660

= 570 / 828

= 570

Step2:

LCM(6, 409) = 2454

GCD(6, 409) = ( 6 x 409 ) / 2454

= 6 / 409

= 6

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 570, 828, 409, 805 is 1
