Make use of GCD Calculator to determine the Greatest Common Divisor of 668, 668, 781, 142 i.e. 1 largest integer that divides all the numbers equally.
GCD of 668, 668, 781, 142 is 1
GCD(668, 668, 781, 142) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 668, 668, 781, 142 is 1
GCD(668, 668, 781, 142) = 1
Given Input numbers are 668, 668, 781, 142
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 71, 142
Greatest Common Divisior
We found the divisors of 668, 668, 781, 142 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 668, 668, 781, 142 is 1.
Therefore, GCD of numbers 668, 668, 781, 142 is 1
Given Input Data is 668, 668, 781, 142
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 668 is 2 x 2 x 167
Prime Factorization of 668 is 2 x 2 x 167
Prime Factorization of 781 is 11 x 71
Prime Factorization of 142 is 2 x 71
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(668, 668) = 668
GCD(668, 668) = ( 668 x 668 ) / 668
GCD(668, 668) = 446224 / 668
GCD(668, 668) = 668
Step2:
Here we consider the GCD from the above i.e. 668 as first number and the next as 781
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(668, 781) = 521708
GCD(668, 781) = ( 668 x 781 ) / 521708
GCD(668, 781) = 521708 / 521708
GCD(668, 781) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 142
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
GCD(1, 142) = 142 / 142
GCD(1, 142) = 1
GCD of 668, 668, 781, 142 is 1
