Given numbers are 720, 978, 569, 641

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 978 are 2 x 3 x 163

Prime factors of 569 are 569

Prime factors of 641 are 641

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

Given numbers are 720, 978, 569, 641

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

Apply this formula for all numbers.

Step1:

LCM(720, 978) = 117360

GCD(720, 978) = ( 720 x 978 ) / 117360

= 720 / 978

= 720

Step2:

LCM(6, 569) = 3414

GCD(6, 569) = ( 6 x 569 ) / 3414

= 6 / 569

= 6

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 720, 978, 569, 641 is 1
