Given numbers are 784, 684, 401, 258

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 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 401 are 401

Prime factors of 258 are 2 x 3 x 43

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

Given numbers are 784, 684, 401, 258

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

Apply this formula for all numbers.

Step1:

LCM(784, 684) = 134064

GCD(784, 684) = ( 784 x 684 ) / 134064

= 784 / 684

= 784

Step2:

LCM(4, 401) = 1604

GCD(4, 401) = ( 4 x 401 ) / 1604

= 4 / 401

= 4

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 784, 684, 401, 258 is 1
