Given numbers are 123, 810, 690, 523

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

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

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 523 are 523

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

Given numbers are 123, 810, 690, 523

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

Apply this formula for all numbers.

Step1:

LCM(123, 810) = 33210

GCD(123, 810) = ( 123 x 810 ) / 33210

= 123 / 810

= 123

Step2:

LCM(3, 690) = 690

GCD(3, 690) = ( 3 x 690 ) / 690

= 3 / 690

= 3

Step3:

LCM(3, 523) = 1569

GCD(3, 523) = ( 3 x 523 ) / 1569

= 3 / 523

= 3

So, Greatest Common Divisor of 123, 810, 690, 523 is 1
