We found the divisors of 54, 77, 91, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 54, 77, 91, 61 is 1.

Therefore, GCD of numbers 54, 77, 91, 61 is 1

Given Input Data is 54, 77, 91, 61

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 77 is 7 x 11

Prime Factorization of 91 is 7 x 13

Prime Factorization of 61 is 61

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(54, 77) = 4158

GCD(54, 77) = ( 54 x 77 ) / 4158

GCD(54, 77) = 4158 / 4158

GCD(54, 77) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 54, 77, 91, 61 is 1
