1, 577
Greatest Common Divisior
We found the divisors of 785, 642, 220, 577 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 785, 642, 220, 577 is 1.
Therefore, GCD of numbers 785, 642, 220, 577 is 1
Given Input Data is 785, 642, 220, 577
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 785 is 5 x 157
Prime Factorization of 642 is 2 x 3 x 107
Prime Factorization of 220 is 2 x 2 x 5 x 11
Prime Factorization of 577 is 577
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(785, 642) = 503970
GCD(785, 642) = ( 785 x 642 ) / 503970
GCD(785, 642) = 503970 / 503970
GCD(785, 642) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 577
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 577) = 577
GCD(1, 577) = ( 1 x 577 ) / 577
GCD(1, 577) = 577 / 577
GCD(1, 577) = 1
GCD of 785, 642, 220, 577 is 1
