Given numbers are 720, 812, 955, 440

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 812 are 2 x 2 x 7 x 29

Prime factors of 955 are 5 x 191

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 720, 812, 955, 440

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

Apply this formula for all numbers.

Step1:

LCM(720, 812) = 146160

GCD(720, 812) = ( 720 x 812 ) / 146160

= 720 / 812

= 720

Step2:

LCM(4, 955) = 3820

GCD(4, 955) = ( 4 x 955 ) / 3820

= 4 / 955

= 4

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 720, 812, 955, 440 is 1
