Given numbers are 817, 623, 253, 990

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

Prime factors of 623 are 7 x 89

Prime factors of 253 are 11 x 23

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

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

Given numbers are 817, 623, 253, 990

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

Apply this formula for all numbers.

Step1:

LCM(817, 623) = 508991

GCD(817, 623) = ( 817 x 623 ) / 508991

= 817 / 623

= 817

Step2:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 817, 623, 253, 990 is 1
