Given numbers are 478, 445, 148, 656

The list of prime factors of all numbers are

Prime factors of 478 are 2 x 239

Prime factors of 445 are 5 x 89

Prime factors of 148 are 2 x 2 x 37

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Given numbers are 478, 445, 148, 656

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

Apply this formula for all numbers.

Step1:

LCM(478, 445) = 212710

GCD(478, 445) = ( 478 x 445 ) / 212710

= 478 / 445

= 478

Step2:

LCM(1, 148) = 148

GCD(1, 148) = ( 1 x 148 ) / 148

= 1 / 148

= 1

Step3:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

So, Greatest Common Divisor of 478, 445, 148, 656 is 1
