Greatest Common Divisior
We found the divisors of 671, 762, 778, 220 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 671, 762, 778, 220 is 1.
Therefore, GCD of numbers 671, 762, 778, 220 is 1
Given Input Data is 671, 762, 778, 220
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 671 is 11 x 61
Prime Factorization of 762 is 2 x 3 x 127
Prime Factorization of 778 is 2 x 389
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(671, 762) = 511302
GCD(671, 762) = ( 671 x 762 ) / 511302
GCD(671, 762) = 511302 / 511302
GCD(671, 762) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 778
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
GCD(1, 778) = 778 / 778
GCD(1, 778) = 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 671, 762, 778, 220 is 1
