Given numbers are 205, 404, 670, 440

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 404 are 2 x 2 x 101

Prime factors of 670 are 2 x 5 x 67

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 205, 404, 670, 440

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

Apply this formula for all numbers.

Step1:

LCM(205, 404) = 82820

GCD(205, 404) = ( 205 x 404 ) / 82820

= 205 / 404

= 205

Step2:

LCM(1, 670) = 670

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

= 1 / 670

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 205, 404, 670, 440 is 1
