GCD of numbers is the greatest common divisor

So, the GCD (140, 430, 13, 520) = 1.

Given numbers are 140, 430, 13, 520

The list of prime factors of all numbers are

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 430 are 2 x 5 x 43

Prime factors of 13 are 13

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 140, 430, 13, 520

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

Apply this formula for all numbers.

Step1:

LCM(140, 430) = 6020

GCD(140, 430) = ( 140 x 430 ) / 6020

= 140 / 430

= 140

Step2:

LCM(10, 13) = 130

GCD(10, 13) = ( 10 x 13 ) / 130

= 10 / 13

= 10

Step3:

LCM(1, 520) = 520

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

= 1 / 520

= 1

So, Greatest Common Divisor of 140, 430, 13, 520 is 1
