Given numbers are 561, 329, 675, 380

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 329 are 7 x 47

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 380 are 2 x 2 x 5 x 19

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

Given numbers are 561, 329, 675, 380

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

Apply this formula for all numbers.

Step1:

LCM(561, 329) = 184569

GCD(561, 329) = ( 561 x 329 ) / 184569

= 561 / 329

= 561

Step2:

LCM(1, 675) = 675

GCD(1, 675) = ( 1 x 675 ) / 675

= 1 / 675

= 1

Step3:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 561, 329, 675, 380 is 1
