Given numbers are 320, 420, 913, 392

The list of prime factors of all numbers are

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 913 are 11 x 83

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 320, 420, 913, 392

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

Apply this formula for all numbers.

Step1:

LCM(320, 420) = 6720

GCD(320, 420) = ( 320 x 420 ) / 6720

= 320 / 420

= 320

Step2:

LCM(20, 913) = 18260

GCD(20, 913) = ( 20 x 913 ) / 18260

= 20 / 913

= 20

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 320, 420, 913, 392 is 1
