Given numbers are 720, 830, 397, 440

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 830 are 2 x 5 x 83

Prime factors of 397 are 397

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 720, 830, 397, 440

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

Apply this formula for all numbers.

Step1:

LCM(720, 830) = 59760

GCD(720, 830) = ( 720 x 830 ) / 59760

= 720 / 830

= 720

Step2:

LCM(10, 397) = 3970

GCD(10, 397) = ( 10 x 397 ) / 3970

= 10 / 397

= 10

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 720, 830, 397, 440 is 1
