Given numbers are 381, 134, 285, 411

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 134 are 2 x 67

Prime factors of 285 are 3 x 5 x 19

Prime factors of 411 are 3 x 137

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

Given numbers are 381, 134, 285, 411

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

Apply this formula for all numbers.

Step1:

LCM(381, 134) = 51054

GCD(381, 134) = ( 381 x 134 ) / 51054

= 381 / 134

= 381

Step2:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

Step3:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

So, Greatest Common Divisor of 381, 134, 285, 411 is 1
