Given numbers are 503, 840, 85, 217

The list of prime factors of all numbers are

Prime factors of 503 are 503

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

Prime factors of 85 are 5 x 17

Prime factors of 217 are 7 x 31

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

Given numbers are 503, 840, 85, 217

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

Apply this formula for all numbers.

Step1:

LCM(503, 840) = 422520

GCD(503, 840) = ( 503 x 840 ) / 422520

= 503 / 840

= 503

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

Step3:

LCM(1, 217) = 217

GCD(1, 217) = ( 1 x 217 ) / 217

= 1 / 217

= 1

So, Greatest Common Divisor of 503, 840, 85, 217 is 1
