We found the divisors of 42, 155, 162, 446 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 42, 155, 162, 446 is 1.

Therefore, GCD of numbers 42, 155, 162, 446 is 1

Given Input Data is 42, 155, 162, 446

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

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 155 is 5 x 31

Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3

Prime Factorization of 446 is 2 x 223

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(42, 155) = 6510

GCD(42, 155) = ( 42 x 155 ) / 6510

GCD(42, 155) = 6510 / 6510

GCD(42, 155) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 162

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

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

GCD(1, 162) = 162 / 162

GCD(1, 162) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 446

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

LCM(1, 446) = 446

GCD(1, 446) = ( 1 x 446 ) / 446

GCD(1, 446) = 446 / 446

GCD(1, 446) = 1

GCD of 42, 155, 162, 446 is 1
