Given numbers are 830, 464, 643, 784

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 643 are 643

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 830, 464, 643, 784

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

Apply this formula for all numbers.

Step1:

LCM(830, 464) = 192560

GCD(830, 464) = ( 830 x 464 ) / 192560

= 830 / 464

= 830

Step2:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

Step3:

LCM(1, 784) = 784

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

= 1 / 784

= 1

So, Greatest Common Divisor of 830, 464, 643, 784 is 1
