Given numbers are 642, 800, 104, 423

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 800 are 2 x 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 104 are 2 x 2 x 2 x 13

Prime factors of 423 are 3 x 3 x 47

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

Given numbers are 642, 800, 104, 423

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

Apply this formula for all numbers.

Step1:

LCM(642, 800) = 256800

GCD(642, 800) = ( 642 x 800 ) / 256800

= 642 / 800

= 642

Step2:

LCM(2, 104) = 104

GCD(2, 104) = ( 2 x 104 ) / 104

= 2 / 104

= 2

Step3:

LCM(2, 423) = 846

GCD(2, 423) = ( 2 x 423 ) / 846

= 2 / 423

= 2

So, Greatest Common Divisor of 642, 800, 104, 423 is 1
