Given numbers are 945, 320, 623, 394

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Prime factors of 623 are 7 x 89

Prime factors of 394 are 2 x 197

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

Given numbers are 945, 320, 623, 394

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

Apply this formula for all numbers.

Step1:

LCM(945, 320) = 60480

GCD(945, 320) = ( 945 x 320 ) / 60480

= 945 / 320

= 945

Step2:

LCM(5, 623) = 3115

GCD(5, 623) = ( 5 x 623 ) / 3115

= 5 / 623

= 5

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 945, 320, 623, 394 is 1
