Make use of GCD Calculator to determine the Greatest Common Divisor of 62, 71, 21, 65 i.e. 1 largest integer that divides all the numbers equally.
GCD of 62, 71, 21, 65 is 1
GCD(62, 71, 21, 65) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 62, 71, 21, 65 is 1
GCD(62, 71, 21, 65) = 1
Given Input numbers are 62, 71, 21, 65
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 62
List of positive integer divisors of 62 that divides 62 without a remainder.
1, 2, 31, 62
Divisors of 71

1, 71
Divisors of 21
List of positive integer divisors of 21 that divides 21 without a remainder.
1, 3, 7, 21
Divisors of 65
List of positive integer divisors of 65 that divides 65 without a remainder.
1, 5, 13, 65
Greatest Common Divisior
We found the divisors of 62, 71, 21, 65 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 62, 71, 21, 65 is 1.
Therefore, GCD of numbers 62, 71, 21, 65 is 1
Given Input Data is 62, 71, 21, 65
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 62 is 2 x 31
Prime Factorization of 71 is 71
Prime Factorization of 21 is 3 x 7
Prime Factorization of 65 is 5 x 13
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(62, 71) = 4402
GCD(62, 71) = ( 62 x 71 ) / 4402
GCD(62, 71) = 4402 / 4402
GCD(62, 71) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 21
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
GCD(1, 21) = 21 / 21
GCD(1, 21) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 65
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 65) = 65
GCD(1, 65) = ( 1 x 65 ) / 65
GCD(1, 65) = 65 / 65
GCD(1, 65) = 1
GCD of 62, 71, 21, 65 is 1
