Given numbers are 509, 210, 486, 840

The list of prime factors of all numbers are

Prime factors of 509 are 509

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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 509, 210, 486, 840

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

Apply this formula for all numbers.

Step1:

LCM(509, 210) = 106890

GCD(509, 210) = ( 509 x 210 ) / 106890

= 509 / 210

= 509

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 509, 210, 486, 840 is 1
