Given numbers are 823, 816, 516, 387

The list of prime factors of all numbers are

Prime factors of 823 are 823

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 516 are 2 x 2 x 3 x 43

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 823, 816, 516, 387

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

Apply this formula for all numbers.

Step1:

LCM(823, 816) = 671568

GCD(823, 816) = ( 823 x 816 ) / 671568

= 823 / 816

= 823

Step2:

LCM(1, 516) = 516

GCD(1, 516) = ( 1 x 516 ) / 516

= 1 / 516

= 1

Step3:

LCM(1, 387) = 387

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

= 1 / 387

= 1

So, Greatest Common Divisor of 823, 816, 516, 387 is 1
