Therefore, GCD of numbers 665, 375, 65, 942 is 1

Given Input Data is 665, 375, 65, 942

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 375 is 3 x 5 x 5 x 5

Prime Factorization of 65 is 5 x 13

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(665, 375) = 49875

GCD(665, 375) = ( 665 x 375 ) / 49875

GCD(665, 375) = 249375 / 49875

GCD(665, 375) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 65

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

LCM(5, 65) = 65

GCD(5, 65) = ( 5 x 65 ) / 65

GCD(5, 65) = 325 / 65

GCD(5, 65) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 942

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

LCM(5, 942) = 4710

GCD(5, 942) = ( 5 x 942 ) / 4710

GCD(5, 942) = 4710 / 4710

GCD(5, 942) = 1

GCD of 665, 375, 65, 942 is 1
