Therefore, GCD of numbers 78, 910, 434, 513 is 1

Given Input Data is 78, 910, 434, 513

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 434 is 2 x 7 x 31

Prime Factorization of 513 is 3 x 3 x 3 x 19

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

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(78, 910) = 2730

GCD(78, 910) = ( 78 x 910 ) / 2730

GCD(78, 910) = 70980 / 2730

GCD(78, 910) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 434

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

LCM(26, 434) = 5642

GCD(26, 434) = ( 26 x 434 ) / 5642

GCD(26, 434) = 11284 / 5642

GCD(26, 434) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 513

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

LCM(2, 513) = 1026

GCD(2, 513) = ( 2 x 513 ) / 1026

GCD(2, 513) = 1026 / 1026

GCD(2, 513) = 1

GCD of 78, 910, 434, 513 is 1
