Given numbers are 561, 710, 649, 486

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 710 are 2 x 5 x 71

Prime factors of 649 are 11 x 59

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

Given numbers are 561, 710, 649, 486

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

Apply this formula for all numbers.

Step1:

LCM(561, 710) = 398310

GCD(561, 710) = ( 561 x 710 ) / 398310

= 561 / 710

= 561

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

So, Greatest Common Divisor of 561, 710, 649, 486 is 1
