Given numbers are 555, 280, 194, 561

The list of prime factors of all numbers are

Prime factors of 555 are 3 x 5 x 37

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

Prime factors of 194 are 2 x 97

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 555, 280, 194, 561

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

Apply this formula for all numbers.

Step1:

LCM(555, 280) = 31080

GCD(555, 280) = ( 555 x 280 ) / 31080

= 555 / 280

= 555

Step2:

LCM(5, 194) = 970

GCD(5, 194) = ( 5 x 194 ) / 970

= 5 / 194

= 5

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 555, 280, 194, 561 is 1
