Given numbers are 642, 495, 604, 723

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 604 are 2 x 2 x 151

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 642, 495, 604, 723

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

Apply this formula for all numbers.

Step1:

LCM(642, 495) = 105930

GCD(642, 495) = ( 642 x 495 ) / 105930

= 642 / 495

= 642

Step2:

LCM(3, 604) = 1812

GCD(3, 604) = ( 3 x 604 ) / 1812

= 3 / 604

= 3

Step3:

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

= 1 / 723

= 1

So, Greatest Common Divisor of 642, 495, 604, 723 is 1
