Given numbers are 821, 746, 510, 254

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 746 are 2 x 373

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

Prime factors of 254 are 2 x 127

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

Given numbers are 821, 746, 510, 254

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

Apply this formula for all numbers.

Step1:

LCM(821, 746) = 612466

GCD(821, 746) = ( 821 x 746 ) / 612466

= 821 / 746

= 821

Step2:

LCM(1, 510) = 510

GCD(1, 510) = ( 1 x 510 ) / 510

= 1 / 510

= 1

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 821, 746, 510, 254 is 1
