Given numbers are 203, 155, 417, 144

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 155 are 5 x 31

Prime factors of 417 are 3 x 139

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 203, 155, 417, 144

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

Apply this formula for all numbers.

Step1:

LCM(203, 155) = 31465

GCD(203, 155) = ( 203 x 155 ) / 31465

= 203 / 155

= 203

Step2:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

Step3:

LCM(1, 144) = 144

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

= 1 / 144

= 1

So, Greatest Common Divisor of 203, 155, 417, 144 is 1
