Given numbers are 391, 150, 784, 458

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 150 are 2 x 3 x 5 x 5

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

Prime factors of 458 are 2 x 229

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

Given numbers are 391, 150, 784, 458

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

Apply this formula for all numbers.

Step1:

LCM(391, 150) = 58650

GCD(391, 150) = ( 391 x 150 ) / 58650

= 391 / 150

= 391

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 391, 150, 784, 458 is 1
