Given numbers are 247, 956, 570, 666

The list of prime factors of all numbers are

Prime factors of 247 are 13 x 19

Prime factors of 956 are 2 x 2 x 239

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

Prime factors of 666 are 2 x 3 x 3 x 37

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

Given numbers are 247, 956, 570, 666

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

Apply this formula for all numbers.

Step1:

LCM(247, 956) = 236132

GCD(247, 956) = ( 247 x 956 ) / 236132

= 247 / 956

= 247

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 666) = 666

GCD(1, 666) = ( 1 x 666 ) / 666

= 1 / 666

= 1

So, Greatest Common Divisor of 247, 956, 570, 666 is 1
