Given numbers are 643, 519, 498, 840

The list of prime factors of all numbers are

Prime factors of 643 are 643

Prime factors of 519 are 3 x 173

Prime factors of 498 are 2 x 3 x 83

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 643, 519, 498, 840

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

Apply this formula for all numbers.

Step1:

LCM(643, 519) = 333717

GCD(643, 519) = ( 643 x 519 ) / 333717

= 643 / 519

= 643

Step2:

LCM(1, 498) = 498

GCD(1, 498) = ( 1 x 498 ) / 498

= 1 / 498

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 643, 519, 498, 840 is 1
