Given numbers are 517, 434, 180, 145

The list of prime factors of all numbers are

Prime factors of 517 are 11 x 47

Prime factors of 434 are 2 x 7 x 31

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 145 are 5 x 29

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

Given numbers are 517, 434, 180, 145

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

Apply this formula for all numbers.

Step1:

LCM(517, 434) = 224378

GCD(517, 434) = ( 517 x 434 ) / 224378

= 517 / 434

= 517

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 517, 434, 180, 145 is 1
