Make use of GCD Calculator to determine the Greatest Common Divisor of 620, 959, 38, 617 i.e. 1 largest integer that divides all the numbers equally.
GCD of 620, 959, 38, 617 is 1
GCD(620, 959, 38, 617) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 620, 959, 38, 617 is 1
GCD(620, 959, 38, 617) = 1
Given Input numbers are 620, 959, 38, 617
To find the GCD of numbers using factoring list out all the divisors of each number

1, 617
Greatest Common Divisior
We found the divisors of 620, 959, 38, 617 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 620, 959, 38, 617 is 1.
Therefore, GCD of numbers 620, 959, 38, 617 is 1
Given Input Data is 620, 959, 38, 617
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 620 is 2 x 2 x 5 x 31
Prime Factorization of 959 is 7 x 137
Prime Factorization of 38 is 2 x 19
Prime Factorization of 617 is 617
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(620, 959) = 594580
GCD(620, 959) = ( 620 x 959 ) / 594580
GCD(620, 959) = 594580 / 594580
GCD(620, 959) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 38
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
GCD(1, 38) = 38 / 38
GCD(1, 38) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 617
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
GCD(1, 617) = 617 / 617
GCD(1, 617) = 1
GCD of 620, 959, 38, 617 is 1
