Given numbers are 561, 378, 468, 550

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 561, 378, 468, 550

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

Apply this formula for all numbers.

Step1:

LCM(561, 378) = 70686

GCD(561, 378) = ( 561 x 378 ) / 70686

= 561 / 378

= 561

Step2:

LCM(3, 468) = 468

GCD(3, 468) = ( 3 x 468 ) / 468

= 3 / 468

= 3

Step3:

LCM(3, 550) = 1650

GCD(3, 550) = ( 3 x 550 ) / 1650

= 3 / 550

= 3

So, Greatest Common Divisor of 561, 378, 468, 550 is 1
