Given numbers are 391, 378, 497, 496

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 497 are 7 x 71

Prime factors of 496 are 2 x 2 x 2 x 2 x 31

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

Given numbers are 391, 378, 497, 496

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

Apply this formula for all numbers.

Step1:

LCM(391, 378) = 147798

GCD(391, 378) = ( 391 x 378 ) / 147798

= 391 / 378

= 391

Step2:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

Step3:

LCM(1, 496) = 496

GCD(1, 496) = ( 1 x 496 ) / 496

= 1 / 496

= 1

So, Greatest Common Divisor of 391, 378, 497, 496 is 1
