Given numbers are 251, 906, 720, 578

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 906 are 2 x 3 x 151

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 251, 906, 720, 578

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

Apply this formula for all numbers.

Step1:

LCM(251, 906) = 227406

GCD(251, 906) = ( 251 x 906 ) / 227406

= 251 / 906

= 251

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 251, 906, 720, 578 is 1
