Therefore, GCD of numbers 70, 155, 853, 528 is 1

Given Input Data is 70, 155, 853, 528

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 155 is 5 x 31

Prime Factorization of 853 is 853

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 x 11

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(70, 155) = 2170

GCD(70, 155) = ( 70 x 155 ) / 2170

GCD(70, 155) = 10850 / 2170

GCD(70, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 853

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

LCM(5, 853) = 4265

GCD(5, 853) = ( 5 x 853 ) / 4265

GCD(5, 853) = 4265 / 4265

GCD(5, 853) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 528

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

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

GCD(1, 528) = 528 / 528

GCD(1, 528) = 1

GCD of 70, 155, 853, 528 is 1
