Given numbers are 423, 770, 385, 771

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 385 are 5 x 7 x 11

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 423, 770, 385, 771

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

Apply this formula for all numbers.

Step1:

LCM(423, 770) = 325710

GCD(423, 770) = ( 423 x 770 ) / 325710

= 423 / 770

= 423

Step2:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

Step3:

LCM(1, 771) = 771

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

= 1 / 771

= 1

So, Greatest Common Divisor of 423, 770, 385, 771 is 1
