Therefore, GCD of numbers 70, 155, 890, 879 is 1

Given Input Data is 70, 155, 890, 879

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 890 is 2 x 5 x 89

Prime Factorization of 879 is 3 x 293

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 890

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

LCM(5, 890) = 890

GCD(5, 890) = ( 5 x 890 ) / 890

GCD(5, 890) = 4450 / 890

GCD(5, 890) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 879

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

LCM(5, 879) = 4395

GCD(5, 879) = ( 5 x 879 ) / 4395

GCD(5, 879) = 4395 / 4395

GCD(5, 879) = 1

GCD of 70, 155, 890, 879 is 1
