Given numbers are 371, 921, 205, 720

The list of prime factors of all numbers are

Prime factors of 371 are 7 x 53

Prime factors of 921 are 3 x 307

Prime factors of 205 are 5 x 41

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 371, 921, 205, 720

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

Apply this formula for all numbers.

Step1:

LCM(371, 921) = 341691

GCD(371, 921) = ( 371 x 921 ) / 341691

= 371 / 921

= 371

Step2:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 371, 921, 205, 720 is 1
