Given numbers are 386, 909, 523, 720

The list of prime factors of all numbers are

Prime factors of 386 are 2 x 193

Prime factors of 909 are 3 x 3 x 101

Prime factors of 523 are 523

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

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

Given numbers are 386, 909, 523, 720

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

Apply this formula for all numbers.

Step1:

LCM(386, 909) = 350874

GCD(386, 909) = ( 386 x 909 ) / 350874

= 386 / 909

= 386

Step2:

LCM(1, 523) = 523

GCD(1, 523) = ( 1 x 523 ) / 523

= 1 / 523

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 386, 909, 523, 720 is 1
