Prime factors of 978 are 2 x 3 x 163

Prime factors of 869 are 11 x 79

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

Given numbers are 561, 504, 978, 869

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

Apply this formula for all numbers.

Step1:

LCM(561, 504) = 94248

GCD(561, 504) = ( 561 x 504 ) / 94248

= 561 / 504

= 561

Step2:

LCM(3, 978) = 978

GCD(3, 978) = ( 3 x 978 ) / 978

= 3 / 978

= 3

Step3:

LCM(3, 869) = 2607

GCD(3, 869) = ( 3 x 869 ) / 2607

= 3 / 869

= 3

So, Greatest Common Divisor of 561, 504, 978, 869 is 1
