Given numbers are 693, 990, 973, 815

The list of prime factors of all numbers are

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 973 are 7 x 139

Prime factors of 815 are 5 x 163

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

Given numbers are 693, 990, 973, 815

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

Apply this formula for all numbers.

Step1:

LCM(693, 990) = 6930

GCD(693, 990) = ( 693 x 990 ) / 6930

= 693 / 990

= 693

Step2:

LCM(99, 973) = 96327

GCD(99, 973) = ( 99 x 973 ) / 96327

= 99 / 973

= 99

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 693, 990, 973, 815 is 1
