Given numbers are 723, 161, 457, 816

The list of prime factors of all numbers are

Prime factors of 723 are 3 x 241

Prime factors of 161 are 7 x 23

Prime factors of 457 are 457

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

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

Given numbers are 723, 161, 457, 816

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

Apply this formula for all numbers.

Step1:

LCM(723, 161) = 116403

GCD(723, 161) = ( 723 x 161 ) / 116403

= 723 / 161

= 723

Step2:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 723, 161, 457, 816 is 1
