Given numbers are 130, 720, 688, 395

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 395 are 5 x 79

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

Given numbers are 130, 720, 688, 395

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

Apply this formula for all numbers.

Step1:

LCM(130, 720) = 9360

GCD(130, 720) = ( 130 x 720 ) / 9360

= 130 / 720

= 130

Step2:

LCM(10, 688) = 3440

GCD(10, 688) = ( 10 x 688 ) / 3440

= 10 / 688

= 10

Step3:

LCM(2, 395) = 790

GCD(2, 395) = ( 2 x 395 ) / 790

= 2 / 395

= 2

So, Greatest Common Divisor of 130, 720, 688, 395 is 1
