Given numbers are 561, 417, 248, 880

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 417 are 3 x 139

Prime factors of 248 are 2 x 2 x 2 x 31

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Given numbers are 561, 417, 248, 880

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

Apply this formula for all numbers.

Step1:

LCM(561, 417) = 77979

GCD(561, 417) = ( 561 x 417 ) / 77979

= 561 / 417

= 561

Step2:

LCM(3, 248) = 744

GCD(3, 248) = ( 3 x 248 ) / 744

= 3 / 248

= 3

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 561, 417, 248, 880 is 1
