Given numbers are 520, 210, 361, 206

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 210 are 2 x 3 x 5 x 7

Prime factors of 361 are 19 x 19

Prime factors of 206 are 2 x 103

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

Given numbers are 520, 210, 361, 206

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

Apply this formula for all numbers.

Step1:

LCM(520, 210) = 10920

GCD(520, 210) = ( 520 x 210 ) / 10920

= 520 / 210

= 520

Step2:

LCM(10, 361) = 3610

GCD(10, 361) = ( 10 x 361 ) / 3610

= 10 / 361

= 10

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 520, 210, 361, 206 is 1
