Given numbers are 545, 253, 612, 123

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 253 are 11 x 23

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

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 545, 253, 612, 123

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

Apply this formula for all numbers.

Step1:

LCM(545, 253) = 137885

GCD(545, 253) = ( 545 x 253 ) / 137885

= 545 / 253

= 545

Step2:

LCM(1, 612) = 612

GCD(1, 612) = ( 1 x 612 ) / 612

= 1 / 612

= 1

Step3:

LCM(1, 123) = 123

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

= 1 / 123

= 1

So, Greatest Common Divisor of 545, 253, 612, 123 is 1
