Given numbers are 130, 655, 456, 869

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 655 are 5 x 131

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 869 are 11 x 79

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

Given numbers are 130, 655, 456, 869

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

Apply this formula for all numbers.

Step1:

LCM(130, 655) = 17030

GCD(130, 655) = ( 130 x 655 ) / 17030

= 130 / 655

= 130

Step2:

LCM(5, 456) = 2280

GCD(5, 456) = ( 5 x 456 ) / 2280

= 5 / 456

= 5

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 130, 655, 456, 869 is 1
