Given numbers are 817, 824, 538, 648

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 824 are 2 x 2 x 2 x 103

Prime factors of 538 are 2 x 269

Prime factors of 648 are 2 x 2 x 2 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 817, 824, 538, 648

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

Apply this formula for all numbers.

Step1:

LCM(817, 824) = 673208

GCD(817, 824) = ( 817 x 824 ) / 673208

= 817 / 824

= 817

Step2:

LCM(1, 538) = 538

GCD(1, 538) = ( 1 x 538 ) / 538

= 1 / 538

= 1

Step3:

LCM(1, 648) = 648

GCD(1, 648) = ( 1 x 648 ) / 648

= 1 / 648

= 1

So, Greatest Common Divisor of 817, 824, 538, 648 is 1
