Given numbers are 510, 788, 861, 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 788 are 2 x 2 x 197

Prime factors of 861 are 3 x 7 x 41

Prime factors of 821 are 821

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

Given numbers are 510, 788, 861, 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, 788) = 200940

GCD(510, 788) = ( 510 x 788 ) / 200940

= 510 / 788

= 510

Step2:

LCM(2, 861) = 1722

GCD(2, 861) = ( 2 x 861 ) / 1722

= 2 / 861

= 2

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 510, 788, 861, 821 is 1
