Given numbers are 784, 345, 398, 801

The list of prime factors of all numbers are

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 345 are 3 x 5 x 23

Prime factors of 398 are 2 x 199

Prime factors of 801 are 3 x 3 x 89

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

Given numbers are 784, 345, 398, 801

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

Apply this formula for all numbers.

Step1:

LCM(784, 345) = 270480

GCD(784, 345) = ( 784 x 345 ) / 270480

= 784 / 345

= 784

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

So, Greatest Common Divisor of 784, 345, 398, 801 is 1
