Given numbers are 123, 143, 455, 570

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 143 are 11 x 13

Prime factors of 455 are 5 x 7 x 13

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

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

Given numbers are 123, 143, 455, 570

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

Apply this formula for all numbers.

Step1:

LCM(123, 143) = 17589

GCD(123, 143) = ( 123 x 143 ) / 17589

= 123 / 143

= 123

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 123, 143, 455, 570 is 1
