We found the divisors of 55, 47, 68, 62 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 55, 47, 68, 62 is 1.

Therefore, GCD of numbers 55, 47, 68, 62 is 1

Given Input Data is 55, 47, 68, 62

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 47 is 47

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 62 is 2 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(55, 47) = 2585

GCD(55, 47) = ( 55 x 47 ) / 2585

GCD(55, 47) = 2585 / 2585

GCD(55, 47) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 68

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

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

GCD(1, 68) = 68 / 68

GCD(1, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 62

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

LCM(1, 62) = 62

GCD(1, 62) = ( 1 x 62 ) / 62

GCD(1, 62) = 62 / 62

GCD(1, 62) = 1

GCD of 55, 47, 68, 62 is 1
