Given numbers are 381, 755, 664, 772

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 755 are 5 x 151

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 381, 755, 664, 772

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

Apply this formula for all numbers.

Step1:

LCM(381, 755) = 287655

GCD(381, 755) = ( 381 x 755 ) / 287655

= 381 / 755

= 381

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 381, 755, 664, 772 is 1
