Given numbers are 325, 519, 69, 420

The list of prime factors of all numbers are

Prime factors of 325 are 5 x 5 x 13

Prime factors of 519 are 3 x 173

Prime factors of 69 are 3 x 23

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

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

Given numbers are 325, 519, 69, 420

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

Apply this formula for all numbers.

Step1:

LCM(325, 519) = 168675

GCD(325, 519) = ( 325 x 519 ) / 168675

= 325 / 519

= 325

Step2:

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

= 1 / 69

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 325, 519, 69, 420 is 1
