Given numbers are 123, 643, 778, 144

The list of prime factors of all numbers are

Prime factors of 123 are 3 x 41

Prime factors of 643 are 643

Prime factors of 778 are 2 x 389

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 123, 643, 778, 144

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

Apply this formula for all numbers.

Step1:

LCM(123, 643) = 79089

GCD(123, 643) = ( 123 x 643 ) / 79089

= 123 / 643

= 123

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 123, 643, 778, 144 is 1
