Given numbers are 720, 845, 436, 357

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 845 are 5 x 13 x 13

Prime factors of 436 are 2 x 2 x 109

Prime factors of 357 are 3 x 7 x 17

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

Given numbers are 720, 845, 436, 357

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

Apply this formula for all numbers.

Step1:

LCM(720, 845) = 121680

GCD(720, 845) = ( 720 x 845 ) / 121680

= 720 / 845

= 720

Step2:

LCM(5, 436) = 2180

GCD(5, 436) = ( 5 x 436 ) / 2180

= 5 / 436

= 5

Step3:

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

= 1 / 357

= 1

So, Greatest Common Divisor of 720, 845, 436, 357 is 1
