Given numbers are 280, 578, 695, 819

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 578 are 2 x 17 x 17

Prime factors of 695 are 5 x 139

Prime factors of 819 are 3 x 3 x 7 x 13

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

Given numbers are 280, 578, 695, 819

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

Apply this formula for all numbers.

Step1:

LCM(280, 578) = 80920

GCD(280, 578) = ( 280 x 578 ) / 80920

= 280 / 578

= 280

Step2:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 280, 578, 695, 819 is 1
