Given numbers are 817, 784, 790, 130

The list of prime factors of all numbers are

Prime factors of 817 are 19 x 43

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

Prime factors of 790 are 2 x 5 x 79

Prime factors of 130 are 2 x 5 x 13

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

Given numbers are 817, 784, 790, 130

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

Apply this formula for all numbers.

Step1:

LCM(817, 784) = 640528

GCD(817, 784) = ( 817 x 784 ) / 640528

= 817 / 784

= 817

Step2:

LCM(1, 790) = 790

GCD(1, 790) = ( 1 x 790 ) / 790

= 1 / 790

= 1

Step3:

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

= 1 / 130

= 1

So, Greatest Common Divisor of 817, 784, 790, 130 is 1
