Given numbers are 578, 209, 480, 771

The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

Prime factors of 209 are 11 x 19

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 771 are 3 x 257

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

Given numbers are 578, 209, 480, 771

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

Apply this formula for all numbers.

Step1:

LCM(578, 209) = 120802

GCD(578, 209) = ( 578 x 209 ) / 120802

= 578 / 209

= 578

Step2:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 578, 209, 480, 771 is 1
