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 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 406 are 2 x 7 x 29

Prime factors of 159 are 3 x 53

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

Given numbers are 945, 688, 406, 159

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

Apply this formula for all numbers.

Step1:

LCM(945, 688) = 650160

GCD(945, 688) = ( 945 x 688 ) / 650160

= 945 / 688

= 945

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 159) = 159

GCD(1, 159) = ( 1 x 159 ) / 159

= 1 / 159

= 1

So, Greatest Common Divisor of 945, 688, 406, 159 is 1
