Given numbers are 278, 450, 381, 321

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 381 are 3 x 127

Prime factors of 321 are 3 x 107

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

Given numbers are 278, 450, 381, 321

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

Apply this formula for all numbers.

Step1:

LCM(278, 450) = 62550

GCD(278, 450) = ( 278 x 450 ) / 62550

= 278 / 450

= 278

Step2:

LCM(2, 381) = 762

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

= 2 / 381

= 2

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 278, 450, 381, 321 is 1
