Given numbers are 623, 478, 288, 663

The list of prime factors of all numbers are

Prime factors of 623 are 7 x 89

Prime factors of 478 are 2 x 239

Prime factors of 288 are 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 663 are 3 x 13 x 17

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

Given numbers are 623, 478, 288, 663

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

Apply this formula for all numbers.

Step1:

LCM(623, 478) = 297794

GCD(623, 478) = ( 623 x 478 ) / 297794

= 623 / 478

= 623

Step2:

LCM(1, 288) = 288

GCD(1, 288) = ( 1 x 288 ) / 288

= 1 / 288

= 1

Step3:

LCM(1, 663) = 663

GCD(1, 663) = ( 1 x 663 ) / 663

= 1 / 663

= 1

So, Greatest Common Divisor of 623, 478, 288, 663 is 1
