Make use of GCD Calculator to determine the Greatest Common Divisor of 68, 62, 29, 20 i.e. 1 largest integer that divides all the numbers equally.
GCD of 68, 62, 29, 20 is 1
GCD(68, 62, 29, 20) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 68, 62, 29, 20 is 1
GCD(68, 62, 29, 20) = 1
Given Input numbers are 68, 62, 29, 20
To find the GCD of numbers using factoring list out all the divisors of each number

1, 29
Divisors of 20
List of positive integer divisors of 20 that divides 20 without a remainder.
1, 2, 4, 5, 10, 20
Greatest Common Divisior
We found the divisors of 68, 62, 29, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 68, 62, 29, 20 is 1.
Therefore, GCD of numbers 68, 62, 29, 20 is 1
Given Input Data is 68, 62, 29, 20
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 68 is 2 x 2 x 17
Prime Factorization of 62 is 2 x 31
Prime Factorization of 29 is 29
Prime Factorization of 20 is 2 x 2 x 5
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(68, 62) = 2108
GCD(68, 62) = ( 68 x 62 ) / 2108
GCD(68, 62) = 4216 / 2108
GCD(68, 62) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 29
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 29) = 58
GCD(2, 29) = ( 2 x 29 ) / 58
GCD(2, 29) = 58 / 58
GCD(2, 29) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
GCD of 68, 62, 29, 20 is 1
