Given numbers are 381, 121, 452, 520

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 121 are 11 x 11

Prime factors of 452 are 2 x 2 x 113

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 381, 121, 452, 520

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

Apply this formula for all numbers.

Step1:

LCM(381, 121) = 46101

GCD(381, 121) = ( 381 x 121 ) / 46101

= 381 / 121

= 381

Step2:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 381, 121, 452, 520 is 1
