Given numbers are 784, 865, 145, 286

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 865 are 5 x 173

Prime factors of 145 are 5 x 29

Prime factors of 286 are 2 x 11 x 13

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

Given numbers are 784, 865, 145, 286

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

Apply this formula for all numbers.

Step1:

LCM(784, 865) = 678160

GCD(784, 865) = ( 784 x 865 ) / 678160

= 784 / 865

= 784

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 784, 865, 145, 286 is 1
