Given numbers are 123, 575, 656, 360

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 575 are 5 x 5 x 23

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 123, 575, 656, 360

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

Apply this formula for all numbers.

Step1:

LCM(123, 575) = 70725

GCD(123, 575) = ( 123 x 575 ) / 70725

= 123 / 575

= 123

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

So, Greatest Common Divisor of 123, 575, 656, 360 is 1
