Given numbers are 130, 478, 155, 438

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 478 are 2 x 239

Prime factors of 155 are 5 x 31

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 130, 478, 155, 438

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

Apply this formula for all numbers.

Step1:

LCM(130, 478) = 31070

GCD(130, 478) = ( 130 x 478 ) / 31070

= 130 / 478

= 130

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 130, 478, 155, 438 is 1
