Given numbers are 278, 370, 816, 289

The list of prime factors of all numbers are

Prime factors of 278 are 2 x 139

Prime factors of 370 are 2 x 5 x 37

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 289 are 17 x 17

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

Given numbers are 278, 370, 816, 289

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

Apply this formula for all numbers.

Step1:

LCM(278, 370) = 51430

GCD(278, 370) = ( 278 x 370 ) / 51430

= 278 / 370

= 278

Step2:

LCM(2, 816) = 816

GCD(2, 816) = ( 2 x 816 ) / 816

= 2 / 816

= 2

Step3:

LCM(2, 289) = 578

GCD(2, 289) = ( 2 x 289 ) / 578

= 2 / 289

= 2

So, Greatest Common Divisor of 278, 370, 816, 289 is 1
