Given numbers are 308, 144, 869, 556

The list of prime factors of all numbers are

Prime factors of 308 are 2 x 2 x 7 x 11

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

Prime factors of 869 are 11 x 79

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 308, 144, 869, 556

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

Apply this formula for all numbers.

Step1:

LCM(308, 144) = 11088

GCD(308, 144) = ( 308 x 144 ) / 11088

= 308 / 144

= 308

Step2:

LCM(4, 869) = 3476

GCD(4, 869) = ( 4 x 869 ) / 3476

= 4 / 869

= 4

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 308, 144, 869, 556 is 1
