Given numbers are 102, 909, 511, 720

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 909 are 3 x 3 x 101

Prime factors of 511 are 7 x 73

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 102, 909, 511, 720

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

Apply this formula for all numbers.

Step1:

LCM(102, 909) = 30906

GCD(102, 909) = ( 102 x 909 ) / 30906

= 102 / 909

= 102

Step2:

LCM(3, 511) = 1533

GCD(3, 511) = ( 3 x 511 ) / 1533

= 3 / 511

= 3

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 102, 909, 511, 720 is 1
