Given numbers are 720, 490, 723, 485

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 490 are 2 x 5 x 7 x 7

Prime factors of 723 are 3 x 241

Prime factors of 485 are 5 x 97

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

Given numbers are 720, 490, 723, 485

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

Apply this formula for all numbers.

Step1:

LCM(720, 490) = 35280

GCD(720, 490) = ( 720 x 490 ) / 35280

= 720 / 490

= 720

Step2:

LCM(10, 723) = 7230

GCD(10, 723) = ( 10 x 723 ) / 7230

= 10 / 723

= 10

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 720, 490, 723, 485 is 1
