Greatest Common Divisior
We found the divisors of 697, 639, 270, 220 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 697, 639, 270, 220 is 1.
Therefore, GCD of numbers 697, 639, 270, 220 is 1
Given Input Data is 697, 639, 270, 220
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 697 is 17 x 41
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5
Prime Factorization of 220 is 2 x 2 x 5 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(697, 639) = 445383
GCD(697, 639) = ( 697 x 639 ) / 445383
GCD(697, 639) = 445383 / 445383
GCD(697, 639) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 270
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 270) = 270
GCD(1, 270) = ( 1 x 270 ) / 270
GCD(1, 270) = 270 / 270
GCD(1, 270) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 220
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
GCD(1, 220) = 220 / 220
GCD(1, 220) = 1
GCD of 697, 639, 270, 220 is 1
