Given numbers are 397, 399, 700, 784

The list of prime factors of all numbers are

Prime factors of 397 are 397

Prime factors of 399 are 3 x 7 x 19

Prime factors of 700 are 2 x 2 x 5 x 5 x 7

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

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

Given numbers are 397, 399, 700, 784

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

Apply this formula for all numbers.

Step1:

LCM(397, 399) = 158403

GCD(397, 399) = ( 397 x 399 ) / 158403

= 397 / 399

= 397

Step2:

LCM(1, 700) = 700

GCD(1, 700) = ( 1 x 700 ) / 700

= 1 / 700

= 1

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 397, 399, 700, 784 is 1
