Given numbers are 305, 957, 390, 400

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 957 are 3 x 11 x 29

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

Given numbers are 305, 957, 390, 400

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

Apply this formula for all numbers.

Step1:

LCM(305, 957) = 291885

GCD(305, 957) = ( 305 x 957 ) / 291885

= 305 / 957

= 305

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

So, Greatest Common Divisor of 305, 957, 390, 400 is 1
