Given numbers are 381, 558, 490, 425

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 425 are 5 x 5 x 17

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

Given numbers are 381, 558, 490, 425

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

Apply this formula for all numbers.

Step1:

LCM(381, 558) = 70866

GCD(381, 558) = ( 381 x 558 ) / 70866

= 381 / 558

= 381

Step2:

LCM(3, 490) = 1470

GCD(3, 490) = ( 3 x 490 ) / 1470

= 3 / 490

= 3

Step3:

LCM(1, 425) = 425

GCD(1, 425) = ( 1 x 425 ) / 425

= 1 / 425

= 1

So, Greatest Common Divisor of 381, 558, 490, 425 is 1
