Given numbers are 406, 744, 923, 689

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 923 are 13 x 71

Prime factors of 689 are 13 x 53

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

Given numbers are 406, 744, 923, 689

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

Apply this formula for all numbers.

Step1:

LCM(406, 744) = 151032

GCD(406, 744) = ( 406 x 744 ) / 151032

= 406 / 744

= 406

Step2:

LCM(2, 923) = 1846

GCD(2, 923) = ( 2 x 923 ) / 1846

= 2 / 923

= 2

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 406, 744, 923, 689 is 1
