Given numbers are 784, 815, 861, 183

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 815 are 5 x 163

Prime factors of 861 are 3 x 7 x 41

Prime factors of 183 are 3 x 61

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

Given numbers are 784, 815, 861, 183

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

Apply this formula for all numbers.

Step1:

LCM(784, 815) = 638960

GCD(784, 815) = ( 784 x 815 ) / 638960

= 784 / 815

= 784

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 183) = 183

GCD(1, 183) = ( 1 x 183 ) / 183

= 1 / 183

= 1

So, Greatest Common Divisor of 784, 815, 861, 183 is 1
