Given Input Data is 790, 158, 680

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 790 is 2 x 5 x 79

Prime Factorization of 158 is 2 x 79

Prime Factorization of 680 is 2 x 2 x 2 x 5 x 17

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

Step1:

Let's calculate the GCD of first two numbers

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

LCM(790, 158) = 790

GCD(790, 158) = ( 790 x 158 ) / 790

GCD(790, 158) = 124820 / 790

GCD(790, 158) = 158

Step2:

Here we consider the GCD from the above i.e. 158 as first number and the next as 680

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

LCM(158, 680) = 53720

GCD(158, 680) = ( 158 x 680 ) / 53720

GCD(158, 680) = 107440 / 53720

GCD(158, 680) = 2

GCD of 790, 158, 680 is 2
