1, 11, 121
Greatest Common Divisior
We found the divisors of 936, 987, 124, 121 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 936, 987, 124, 121 is 1.
Therefore, GCD of numbers 936, 987, 124, 121 is 1
Given Input Data is 936, 987, 124, 121
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13
Prime Factorization of 987 is 3 x 7 x 47
Prime Factorization of 124 is 2 x 2 x 31
Prime Factorization of 121 is 11 x 11
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(936, 987) = 307944
GCD(936, 987) = ( 936 x 987 ) / 307944
GCD(936, 987) = 923832 / 307944
GCD(936, 987) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 124
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 124) = 372
GCD(3, 124) = ( 3 x 124 ) / 372
GCD(3, 124) = 372 / 372
GCD(3, 124) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 121
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
GCD(1, 121) = 121 / 121
GCD(1, 121) = 1
GCD of 936, 987, 124, 121 is 1
