Given numbers are 128, 520, 194, 381

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Prime factors of 194 are 2 x 97

Prime factors of 381 are 3 x 127

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

Given numbers are 128, 520, 194, 381

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

Apply this formula for all numbers.

Step1:

LCM(128, 520) = 8320

GCD(128, 520) = ( 128 x 520 ) / 8320

= 128 / 520

= 128

Step2:

LCM(8, 194) = 776

GCD(8, 194) = ( 8 x 194 ) / 776

= 8 / 194

= 8

Step3:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2

So, Greatest Common Divisor of 128, 520, 194, 381 is 1
