1, 647
Greatest Common Divisior
We found the divisors of 803, 117, 690, 647 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 803, 117, 690, 647 is 1.
Therefore, GCD of numbers 803, 117, 690, 647 is 1
Given Input Data is 803, 117, 690, 647
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 803 is 11 x 73
Prime Factorization of 117 is 3 x 3 x 13
Prime Factorization of 690 is 2 x 3 x 5 x 23
Prime Factorization of 647 is 647
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(803, 117) = 93951
GCD(803, 117) = ( 803 x 117 ) / 93951
GCD(803, 117) = 93951 / 93951
GCD(803, 117) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 690
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
GCD(1, 690) = 690 / 690
GCD(1, 690) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 647
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 647) = 647
GCD(1, 647) = ( 1 x 647 ) / 647
GCD(1, 647) = 647 / 647
GCD(1, 647) = 1
GCD of 803, 117, 690, 647 is 1
