Therefore, GCD of numbers 215, 885, 61, 942 is 1

Given Input Data is 215, 885, 61, 942

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 61 is 61

Prime Factorization of 942 is 2 x 3 x 157

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(215, 885) = 38055

GCD(215, 885) = ( 215 x 885 ) / 38055

GCD(215, 885) = 190275 / 38055

GCD(215, 885) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 61

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

LCM(5, 61) = 305

GCD(5, 61) = ( 5 x 61 ) / 305

GCD(5, 61) = 305 / 305

GCD(5, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 942

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

LCM(1, 942) = 942

GCD(1, 942) = ( 1 x 942 ) / 942

GCD(1, 942) = 942 / 942

GCD(1, 942) = 1

GCD of 215, 885, 61, 942 is 1
