Given numbers are 815, 817, 387, 496

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 817 are 19 x 43

Prime factors of 387 are 3 x 3 x 43

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

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

Given numbers are 815, 817, 387, 496

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

Apply this formula for all numbers.

Step1:

LCM(815, 817) = 665855

GCD(815, 817) = ( 815 x 817 ) / 665855

= 815 / 817

= 815

Step2:

LCM(1, 387) = 387

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

= 1 / 387

= 1

Step3:

LCM(1, 496) = 496

GCD(1, 496) = ( 1 x 496 ) / 496

= 1 / 496

= 1

So, Greatest Common Divisor of 815, 817, 387, 496 is 1
