Given numbers are 406, 744, 560, 391

The list of prime factors of all numbers are

Prime factors of 406 are 2 x 7 x 29

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 391 are 17 x 23

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

Given numbers are 406, 744, 560, 391

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

Apply this formula for all numbers.

Step1:

LCM(406, 744) = 151032

GCD(406, 744) = ( 406 x 744 ) / 151032

= 406 / 744

= 406

Step2:

LCM(2, 560) = 560

GCD(2, 560) = ( 2 x 560 ) / 560

= 2 / 560

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 406, 744, 560, 391 is 1
