Given numbers are 390, 402, 957, 703

The list of prime factors of all numbers are

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

Prime factors of 402 are 2 x 3 x 67

Prime factors of 957 are 3 x 11 x 29

Prime factors of 703 are 19 x 37

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

Given numbers are 390, 402, 957, 703

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

Apply this formula for all numbers.

Step1:

LCM(390, 402) = 26130

GCD(390, 402) = ( 390 x 402 ) / 26130

= 390 / 402

= 390

Step2:

LCM(6, 957) = 1914

GCD(6, 957) = ( 6 x 957 ) / 1914

= 6 / 957

= 6

Step3:

LCM(3, 703) = 2109

GCD(3, 703) = ( 3 x 703 ) / 2109

= 3 / 703

= 3

So, Greatest Common Divisor of 390, 402, 957, 703 is 1
