Given numbers are 720, 220, 759, 478

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 220 are 2 x 2 x 5 x 11

Prime factors of 759 are 3 x 11 x 23

Prime factors of 478 are 2 x 239

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

Given numbers are 720, 220, 759, 478

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

Apply this formula for all numbers.

Step1:

LCM(720, 220) = 7920

GCD(720, 220) = ( 720 x 220 ) / 7920

= 720 / 220

= 720

Step2:

LCM(20, 759) = 15180

GCD(20, 759) = ( 20 x 759 ) / 15180

= 20 / 759

= 20

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 720, 220, 759, 478 is 1
