Given numbers are 815, 351, 387, 102

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 387 are 3 x 3 x 43

Prime factors of 102 are 2 x 3 x 17

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

Given numbers are 815, 351, 387, 102

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

Apply this formula for all numbers.

Step1:

LCM(815, 351) = 286065

GCD(815, 351) = ( 815 x 351 ) / 286065

= 815 / 351

= 815

Step2:

LCM(1, 387) = 387

GCD(1, 387) = ( 1 x 387 ) / 387

= 1 / 387

= 1

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 815, 351, 387, 102 is 1
