Given numbers are 345, 396, 945, 430

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

Prime factors of 396 are 2 x 2 x 3 x 3 x 11

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

Prime factors of 430 are 2 x 5 x 43

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

Given numbers are 345, 396, 945, 430

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

Apply this formula for all numbers.

Step1:

LCM(345, 396) = 45540

GCD(345, 396) = ( 345 x 396 ) / 45540

= 345 / 396

= 345

Step2:

LCM(3, 945) = 945

GCD(3, 945) = ( 3 x 945 ) / 945

= 3 / 945

= 3

Step3:

LCM(3, 430) = 1290

GCD(3, 430) = ( 3 x 430 ) / 1290

= 3 / 430

= 3

So, Greatest Common Divisor of 345, 396, 945, 430 is 1
