Given numbers are 720, 153, 666, 818

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 153 are 3 x 3 x 17

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 818 are 2 x 409

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

Given numbers are 720, 153, 666, 818

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

Apply this formula for all numbers.

Step1:

LCM(720, 153) = 12240

GCD(720, 153) = ( 720 x 153 ) / 12240

= 720 / 153

= 720

Step2:

LCM(9, 666) = 666

GCD(9, 666) = ( 9 x 666 ) / 666

= 9 / 666

= 9

Step3:

LCM(9, 818) = 7362

GCD(9, 818) = ( 9 x 818 ) / 7362

= 9 / 818

= 9

So, Greatest Common Divisor of 720, 153, 666, 818 is 1
