Given numbers are 818, 156, 441, 720

The list of prime factors of all numbers are

Prime factors of 818 are 2 x 409

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 441 are 3 x 3 x 7 x 7

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 818, 156, 441, 720

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

Apply this formula for all numbers.

Step1:

LCM(818, 156) = 63804

GCD(818, 156) = ( 818 x 156 ) / 63804

= 818 / 156

= 818

Step2:

LCM(2, 441) = 882

GCD(2, 441) = ( 2 x 441 ) / 882

= 2 / 441

= 2

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 818, 156, 441, 720 is 1
