Given numbers are 123, 745, 161, 477

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 745 are 5 x 149

Prime factors of 161 are 7 x 23

Prime factors of 477 are 3 x 3 x 53

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

Given numbers are 123, 745, 161, 477

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

Apply this formula for all numbers.

Step1:

LCM(123, 745) = 91635

GCD(123, 745) = ( 123 x 745 ) / 91635

= 123 / 745

= 123

Step2:

LCM(1, 161) = 161

GCD(1, 161) = ( 1 x 161 ) / 161

= 1 / 161

= 1

Step3:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

So, Greatest Common Divisor of 123, 745, 161, 477 is 1
