Make use of GCD Calculator to determine the Greatest Common Divisor of 639, 669, 52, 664 i.e. 1 largest integer that divides all the numbers equally.
GCD of 639, 669, 52, 664 is 1
GCD(639, 669, 52, 664) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 639, 669, 52, 664 is 1
GCD(639, 669, 52, 664) = 1
Given Input numbers are 639, 669, 52, 664
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 8, 83, 166, 332, 664
Greatest Common Divisior
We found the divisors of 639, 669, 52, 664 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 639, 669, 52, 664 is 1.
Therefore, GCD of numbers 639, 669, 52, 664 is 1
Given Input Data is 639, 669, 52, 664
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 669 is 3 x 223
Prime Factorization of 52 is 2 x 2 x 13
Prime Factorization of 664 is 2 x 2 x 2 x 83
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(639, 669) = 142497
GCD(639, 669) = ( 639 x 669 ) / 142497
GCD(639, 669) = 427491 / 142497
GCD(639, 669) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 52
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 52) = 156
GCD(3, 52) = ( 3 x 52 ) / 156
GCD(3, 52) = 156 / 156
GCD(3, 52) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 664
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
GCD(1, 664) = 664 / 664
GCD(1, 664) = 1
GCD of 639, 669, 52, 664 is 1
