Given numbers are 570, 546, 247, 309

The list of prime factors of all numbers are

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 546 are 2 x 3 x 7 x 13

Prime factors of 247 are 13 x 19

Prime factors of 309 are 3 x 103

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

Given numbers are 570, 546, 247, 309

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

Apply this formula for all numbers.

Step1:

LCM(570, 546) = 51870

GCD(570, 546) = ( 570 x 546 ) / 51870

= 570 / 546

= 570

Step2:

LCM(6, 247) = 1482

GCD(6, 247) = ( 6 x 247 ) / 1482

= 6 / 247

= 6

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 570, 546, 247, 309 is 1
