Given numbers are 923, 665, 638, 684

The list of prime factors of all numbers are

Prime factors of 923 are 13 x 71

Prime factors of 665 are 5 x 7 x 19

Prime factors of 638 are 2 x 11 x 29

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 923, 665, 638, 684

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

Apply this formula for all numbers.

Step1:

LCM(923, 665) = 613795

GCD(923, 665) = ( 923 x 665 ) / 613795

= 923 / 665

= 923

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 923, 665, 638, 684 is 1
