Given numbers are 381, 473, 854, 721

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 473 are 11 x 43

Prime factors of 854 are 2 x 7 x 61

Prime factors of 721 are 7 x 103

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

Given numbers are 381, 473, 854, 721

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

Apply this formula for all numbers.

Step1:

LCM(381, 473) = 180213

GCD(381, 473) = ( 381 x 473 ) / 180213

= 381 / 473

= 381

Step2:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

Step3:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

So, Greatest Common Divisor of 381, 473, 854, 721 is 1
