Given numbers are 720, 653, 997, 809

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 653 are 653

Prime factors of 997 are 997

Prime factors of 809 are 809

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

Given numbers are 720, 653, 997, 809

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

Apply this formula for all numbers.

Step1:

LCM(720, 653) = 470160

GCD(720, 653) = ( 720 x 653 ) / 470160

= 720 / 653

= 720

Step2:

LCM(1, 997) = 997

GCD(1, 997) = ( 1 x 997 ) / 997

= 1 / 997

= 1

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 720, 653, 997, 809 is 1
