Given numbers are 510, 141, 687, 821

The list of prime factors of all numbers are

Prime factors of 510 are 2 x 3 x 5 x 17

Prime factors of 141 are 3 x 47

Prime factors of 687 are 3 x 229

Prime factors of 821 are 821

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

Given numbers are 510, 141, 687, 821

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

Apply this formula for all numbers.

Step1:

LCM(510, 141) = 23970

GCD(510, 141) = ( 510 x 141 ) / 23970

= 510 / 141

= 510

Step2:

LCM(3, 687) = 687

GCD(3, 687) = ( 3 x 687 ) / 687

= 3 / 687

= 3

Step3:

LCM(3, 821) = 2463

GCD(3, 821) = ( 3 x 821 ) / 2463

= 3 / 821

= 3

So, Greatest Common Divisor of 510, 141, 687, 821 is 1
