Greatest Common Divisior
We found the divisors of 977, 688, 251 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 977, 688, 251 is 1.
Therefore, GCD of numbers 977, 688, 251 is 1
Given Input Data is 977, 688, 251
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 977 is 977
Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43
Prime Factorization of 251 is 251
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(977, 688) = 672176
GCD(977, 688) = ( 977 x 688 ) / 672176
GCD(977, 688) = 672176 / 672176
GCD(977, 688) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 251
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
GCD(1, 251) = 251 / 251
GCD(1, 251) = 1
GCD of 977, 688, 251 is 1
