Given numbers are 720, 855, 795, 434

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 855 are 3 x 3 x 5 x 19

Prime factors of 795 are 3 x 5 x 53

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 720, 855, 795, 434

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

Apply this formula for all numbers.

Step1:

LCM(720, 855) = 13680

GCD(720, 855) = ( 720 x 855 ) / 13680

= 720 / 855

= 720

Step2:

LCM(45, 795) = 2385

GCD(45, 795) = ( 45 x 795 ) / 2385

= 45 / 795

= 45

Step3:

LCM(15, 434) = 6510

GCD(15, 434) = ( 15 x 434 ) / 6510

= 15 / 434

= 15

So, Greatest Common Divisor of 720, 855, 795, 434 is 1
