So the Greatest Common Divisior 96, 78, 68, 70 is 2.

Therefore, GCD of numbers 96, 78, 68, 70 is 2

Given Input Data is 96, 78, 68, 70

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

Prime Factorization of 96 is 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 70 is 2 x 5 x 7

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(96, 78) = 1248

GCD(96, 78) = ( 96 x 78 ) / 1248

GCD(96, 78) = 7488 / 1248

GCD(96, 78) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 68

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

LCM(6, 68) = 204

GCD(6, 68) = ( 6 x 68 ) / 204

GCD(6, 68) = 408 / 204

GCD(6, 68) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 70

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

LCM(2, 70) = 70

GCD(2, 70) = ( 2 x 70 ) / 70

GCD(2, 70) = 140 / 70

GCD(2, 70) = 2

GCD of 96, 78, 68, 70 is 2
