Given numbers are 123, 815, 556, 265

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 815 are 5 x 163

Prime factors of 556 are 2 x 2 x 139

Prime factors of 265 are 5 x 53

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

Given numbers are 123, 815, 556, 265

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

Apply this formula for all numbers.

Step1:

LCM(123, 815) = 100245

GCD(123, 815) = ( 123 x 815 ) / 100245

= 123 / 815

= 123

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

So, Greatest Common Divisor of 123, 815, 556, 265 is 1
