Given numbers are 810, 897, 747, 557

The list of prime factors of all numbers are

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

Prime factors of 897 are 3 x 13 x 23

Prime factors of 747 are 3 x 3 x 83

Prime factors of 557 are 557

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

Given numbers are 810, 897, 747, 557

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

Apply this formula for all numbers.

Step1:

LCM(810, 897) = 242190

GCD(810, 897) = ( 810 x 897 ) / 242190

= 810 / 897

= 810

Step2:

LCM(3, 747) = 747

GCD(3, 747) = ( 3 x 747 ) / 747

= 3 / 747

= 3

Step3:

LCM(3, 557) = 1671

GCD(3, 557) = ( 3 x 557 ) / 1671

= 3 / 557

= 3

So, Greatest Common Divisor of 810, 897, 747, 557 is 1
