Given numbers are 687, 816, 639, 506

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

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

Prime factors of 639 are 3 x 3 x 71

Prime factors of 506 are 2 x 11 x 23

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

Given numbers are 687, 816, 639, 506

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

Apply this formula for all numbers.

Step1:

LCM(687, 816) = 186864

GCD(687, 816) = ( 687 x 816 ) / 186864

= 687 / 816

= 687

Step2:

LCM(3, 639) = 639

GCD(3, 639) = ( 3 x 639 ) / 639

= 3 / 639

= 3

Step3:

LCM(3, 506) = 1518

GCD(3, 506) = ( 3 x 506 ) / 1518

= 3 / 506

= 3

So, Greatest Common Divisor of 687, 816, 639, 506 is 1
