Given numbers are 642, 519, 816, 364

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 519 are 3 x 173

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

Prime factors of 364 are 2 x 2 x 7 x 13

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

Given numbers are 642, 519, 816, 364

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

Apply this formula for all numbers.

Step1:

LCM(642, 519) = 111066

GCD(642, 519) = ( 642 x 519 ) / 111066

= 642 / 519

= 642

Step2:

LCM(3, 816) = 816

GCD(3, 816) = ( 3 x 816 ) / 816

= 3 / 816

= 3

Step3:

LCM(3, 364) = 1092

GCD(3, 364) = ( 3 x 364 ) / 1092

= 3 / 364

= 3

So, Greatest Common Divisor of 642, 519, 816, 364 is 1
