We found the divisors of 355, 437, 646, 186 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 355, 437, 646, 186 is 1.

Therefore, GCD of numbers 355, 437, 646, 186 is 1

Given Input Data is 355, 437, 646, 186

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 437 is 19 x 23

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 186 is 2 x 3 x 31

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(355, 437) = 155135

GCD(355, 437) = ( 355 x 437 ) / 155135

GCD(355, 437) = 155135 / 155135

GCD(355, 437) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 646

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

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

GCD(1, 646) = 646 / 646

GCD(1, 646) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 186

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

LCM(1, 186) = 186

GCD(1, 186) = ( 1 x 186 ) / 186

GCD(1, 186) = 186 / 186

GCD(1, 186) = 1

GCD of 355, 437, 646, 186 is 1
