Given numbers are 520, 606, 388, 409

The list of prime factors of all numbers are

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

Prime factors of 606 are 2 x 3 x 101

Prime factors of 388 are 2 x 2 x 97

Prime factors of 409 are 409

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

Given numbers are 520, 606, 388, 409

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

Apply this formula for all numbers.

Step1:

LCM(520, 606) = 157560

GCD(520, 606) = ( 520 x 606 ) / 157560

= 520 / 606

= 520

Step2:

LCM(2, 388) = 388

GCD(2, 388) = ( 2 x 388 ) / 388

= 2 / 388

= 2

Step3:

LCM(2, 409) = 818

GCD(2, 409) = ( 2 x 409 ) / 818

= 2 / 409

= 2

So, Greatest Common Divisor of 520, 606, 388, 409 is 1
