Given numbers are 161, 711, 575, 123

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 711 are 3 x 3 x 79

Prime factors of 575 are 5 x 5 x 23

Prime factors of 123 are 3 x 41

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

Given numbers are 161, 711, 575, 123

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

Apply this formula for all numbers.

Step1:

LCM(161, 711) = 114471

GCD(161, 711) = ( 161 x 711 ) / 114471

= 161 / 711

= 161

Step2:

LCM(1, 575) = 575

GCD(1, 575) = ( 1 x 575 ) / 575

= 1 / 575

= 1

Step3:

LCM(1, 123) = 123

GCD(1, 123) = ( 1 x 123 ) / 123

= 1 / 123

= 1

So, Greatest Common Divisor of 161, 711, 575, 123 is 1
