Given numbers are 130, 380, 988, 403

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 403 are 13 x 31

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

Given numbers are 130, 380, 988, 403

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

Apply this formula for all numbers.

Step1:

LCM(130, 380) = 4940

GCD(130, 380) = ( 130 x 380 ) / 4940

= 130 / 380

= 130

Step2:

LCM(10, 988) = 4940

GCD(10, 988) = ( 10 x 988 ) / 4940

= 10 / 988

= 10

Step3:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

So, Greatest Common Divisor of 130, 380, 988, 403 is 1
