Given numbers are 561, 280, 487, 996

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

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

Prime factors of 487 are 487

Prime factors of 996 are 2 x 2 x 3 x 83

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

Given numbers are 561, 280, 487, 996

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

Apply this formula for all numbers.

Step1:

LCM(561, 280) = 157080

GCD(561, 280) = ( 561 x 280 ) / 157080

= 561 / 280

= 561

Step2:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

Step3:

LCM(1, 996) = 996

GCD(1, 996) = ( 1 x 996 ) / 996

= 1 / 996

= 1

So, Greatest Common Divisor of 561, 280, 487, 996 is 1
