Given numbers are 390, 478, 254, 611

The list of prime factors of all numbers are

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

Prime factors of 478 are 2 x 239

Prime factors of 254 are 2 x 127

Prime factors of 611 are 13 x 47

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

Given numbers are 390, 478, 254, 611

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

Apply this formula for all numbers.

Step1:

LCM(390, 478) = 93210

GCD(390, 478) = ( 390 x 478 ) / 93210

= 390 / 478

= 390

Step2:

LCM(2, 254) = 254

GCD(2, 254) = ( 2 x 254 ) / 254

= 2 / 254

= 2

Step3:

LCM(2, 611) = 1222

GCD(2, 611) = ( 2 x 611 ) / 1222

= 2 / 611

= 2

So, Greatest Common Divisor of 390, 478, 254, 611 is 1
