Given numbers are 513, 646, 209, 280

The list of prime factors of all numbers are

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 646 are 2 x 17 x 19

Prime factors of 209 are 11 x 19

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

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

Given numbers are 513, 646, 209, 280

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

Apply this formula for all numbers.

Step1:

LCM(513, 646) = 17442

GCD(513, 646) = ( 513 x 646 ) / 17442

= 513 / 646

= 513

Step2:

LCM(19, 209) = 209

GCD(19, 209) = ( 19 x 209 ) / 209

= 19 / 209

= 19

Step3:

LCM(19, 280) = 5320

GCD(19, 280) = ( 19 x 280 ) / 5320

= 19 / 280

= 19

So, Greatest Common Divisor of 513, 646, 209, 280 is 1
