Given numbers are 503, 458, 840, 643

The list of prime factors of all numbers are

Prime factors of 503 are 503

Prime factors of 458 are 2 x 229

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

Prime factors of 643 are 643

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

Given numbers are 503, 458, 840, 643

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

Apply this formula for all numbers.

Step1:

LCM(503, 458) = 230374

GCD(503, 458) = ( 503 x 458 ) / 230374

= 503 / 458

= 503

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 503, 458, 840, 643 is 1
