Given numbers are 351, 247, 665, 243

The list of prime factors of all numbers are

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 247 are 13 x 19

Prime factors of 665 are 5 x 7 x 19

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 351, 247, 665, 243

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

Apply this formula for all numbers.

Step1:

LCM(351, 247) = 6669

GCD(351, 247) = ( 351 x 247 ) / 6669

= 351 / 247

= 351

Step2:

LCM(13, 665) = 8645

GCD(13, 665) = ( 13 x 665 ) / 8645

= 13 / 665

= 13

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 351, 247, 665, 243 is 1
