Given numbers are 130, 869, 147, 520

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 869 are 11 x 79

Prime factors of 147 are 3 x 7 x 7

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 130, 869, 147, 520

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

Apply this formula for all numbers.

Step1:

LCM(130, 869) = 112970

GCD(130, 869) = ( 130 x 869 ) / 112970

= 130 / 869

= 130

Step2:

LCM(1, 147) = 147

GCD(1, 147) = ( 1 x 147 ) / 147

= 1 / 147

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 130, 869, 147, 520 is 1
