The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 345 are 3 x 5 x 23

Prime factors of 670 are 2 x 5 x 67

Prime factors of 445 are 5 x 89

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

Given numbers are 178, 345, 670, 445

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

Apply this formula for all numbers.

Step1:

LCM(178, 345) = 61410

GCD(178, 345) = ( 178 x 345 ) / 61410

= 178 / 345

= 178

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

Step3:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 178, 345, 670, 445 is 1
