Given numbers are 815, 564, 342, 247

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 247 are 13 x 19

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

Given numbers are 815, 564, 342, 247

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

Apply this formula for all numbers.

Step1:

LCM(815, 564) = 459660

GCD(815, 564) = ( 815 x 564 ) / 459660

= 815 / 564

= 815

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1

So, Greatest Common Divisor of 815, 564, 342, 247 is 1
