Given numbers are 435, 443, 720, 921

The list of prime factors of all numbers are

Prime factors of 435 are 3 x 5 x 29

Prime factors of 443 are 443

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 921 are 3 x 307

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

Given numbers are 435, 443, 720, 921

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

Apply this formula for all numbers.

Step1:

LCM(435, 443) = 192705

GCD(435, 443) = ( 435 x 443 ) / 192705

= 435 / 443

= 435

Step2:

LCM(1, 720) = 720

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

= 1 / 720

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 435, 443, 720, 921 is 1
