Given numbers are 420, 449, 933, 771

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 449 are 449

Prime factors of 933 are 3 x 311

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 420, 449, 933, 771

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

Apply this formula for all numbers.

Step1:

LCM(420, 449) = 188580

GCD(420, 449) = ( 420 x 449 ) / 188580

= 420 / 449

= 420

Step2:

LCM(1, 933) = 933

GCD(1, 933) = ( 1 x 933 ) / 933

= 1 / 933

= 1

Step3:

LCM(1, 771) = 771

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

= 1 / 771

= 1

So, Greatest Common Divisor of 420, 449, 933, 771 is 1
