Given numbers are 320, 138, 473, 745

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 138 are 2 x 3 x 23

Prime factors of 473 are 11 x 43

Prime factors of 745 are 5 x 149

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

Given numbers are 320, 138, 473, 745

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

Apply this formula for all numbers.

Step1:

LCM(320, 138) = 22080

GCD(320, 138) = ( 320 x 138 ) / 22080

= 320 / 138

= 320

Step2:

LCM(2, 473) = 946

GCD(2, 473) = ( 2 x 473 ) / 946

= 2 / 473

= 2

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 320, 138, 473, 745 is 1
