Given numbers are 440, 606, 398, 491

The list of prime factors of all numbers are

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

Prime factors of 606 are 2 x 3 x 101

Prime factors of 398 are 2 x 199

Prime factors of 491 are 491

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

Given numbers are 440, 606, 398, 491

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

Apply this formula for all numbers.

Step1:

LCM(440, 606) = 133320

GCD(440, 606) = ( 440 x 606 ) / 133320

= 440 / 606

= 440

Step2:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

Step3:

LCM(2, 491) = 982

GCD(2, 491) = ( 2 x 491 ) / 982

= 2 / 491

= 2

So, Greatest Common Divisor of 440, 606, 398, 491 is 1
