Given numbers are 638, 816, 610, 723

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 610 are 2 x 5 x 61

Prime factors of 723 are 3 x 241

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

Given numbers are 638, 816, 610, 723

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

Apply this formula for all numbers.

Step1:

LCM(638, 816) = 260304

GCD(638, 816) = ( 638 x 816 ) / 260304

= 638 / 816

= 638

Step2:

LCM(2, 610) = 610

GCD(2, 610) = ( 2 x 610 ) / 610

= 2 / 610

= 2

Step3:

LCM(2, 723) = 1446

GCD(2, 723) = ( 2 x 723 ) / 1446

= 2 / 723

= 2

So, Greatest Common Divisor of 638, 816, 610, 723 is 1
