Given numbers are 561, 480, 679, 994

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 679 are 7 x 97

Prime factors of 994 are 2 x 7 x 71

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

Given numbers are 561, 480, 679, 994

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

Apply this formula for all numbers.

Step1:

LCM(561, 480) = 89760

GCD(561, 480) = ( 561 x 480 ) / 89760

= 561 / 480

= 561

Step2:

LCM(3, 679) = 2037

GCD(3, 679) = ( 3 x 679 ) / 2037

= 3 / 679

= 3

Step3:

LCM(1, 994) = 994

GCD(1, 994) = ( 1 x 994 ) / 994

= 1 / 994

= 1

So, Greatest Common Divisor of 561, 480, 679, 994 is 1
