Given numbers are 454, 278, 550, 395

The list of prime factors of all numbers are

Prime factors of 454 are 2 x 227

Prime factors of 278 are 2 x 139

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 395 are 5 x 79

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

Given numbers are 454, 278, 550, 395

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

Apply this formula for all numbers.

Step1:

LCM(454, 278) = 63106

GCD(454, 278) = ( 454 x 278 ) / 63106

= 454 / 278

= 454

Step2:

LCM(2, 550) = 550

GCD(2, 550) = ( 2 x 550 ) / 550

= 2 / 550

= 2

Step3:

LCM(2, 395) = 790

GCD(2, 395) = ( 2 x 395 ) / 790

= 2 / 395

= 2

So, Greatest Common Divisor of 454, 278, 550, 395 is 1
