Given numbers are 720, 661, 817, 568

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 661 are 661

Prime factors of 817 are 19 x 43

Prime factors of 568 are 2 x 2 x 2 x 71

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

Given numbers are 720, 661, 817, 568

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

Apply this formula for all numbers.

Step1:

LCM(720, 661) = 475920

GCD(720, 661) = ( 720 x 661 ) / 475920

= 720 / 661

= 720

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

So, Greatest Common Divisor of 720, 661, 817, 568 is 1
