Given numbers are 154, 390, 381, 472

The list of prime factors of all numbers are

Prime factors of 154 are 2 x 7 x 11

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 381 are 3 x 127

Prime factors of 472 are 2 x 2 x 2 x 59

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

Given numbers are 154, 390, 381, 472

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

Apply this formula for all numbers.

Step1:

LCM(154, 390) = 30030

GCD(154, 390) = ( 154 x 390 ) / 30030

= 154 / 390

= 154

Step2:

LCM(2, 381) = 762

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

= 2 / 381

= 2

Step3:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

So, Greatest Common Divisor of 154, 390, 381, 472 is 1
