Make use of GCD Calculator to determine the Greatest Common Divisor of 30, 7, 60, 72 i.e. 1 largest integer that divides all the numbers equally.
GCD of 30, 7, 60, 72 is 1
GCD(30, 7, 60, 72) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 30, 7, 60, 72 is 1
GCD(30, 7, 60, 72) = 1
Given Input numbers are 30, 7, 60, 72
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Divisors of 7
List of positive integer divisors of 7 that divides 7 without a remainder.
1, 7
Divisors of 60
List of positive integer divisors of 60 that divides 60 without a remainder.
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Divisors of 72
List of positive integer divisors of 72 that divides 72 without a remainder.
1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Greatest Common Divisior
We found the divisors of 30, 7, 60, 72 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 30, 7, 60, 72 is 1.
Therefore, GCD of numbers 30, 7, 60, 72 is 1
Given Input Data is 30, 7, 60, 72
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 30 is 2 x 3 x 5
Prime Factorization of 7 is 7
Prime Factorization of 60 is 2 x 2 x 3 x 5
Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3
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(30, 7) = 210
GCD(30, 7) = ( 30 x 7 ) / 210
GCD(30, 7) = 210 / 210
GCD(30, 7) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 60
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 60) = 60
GCD(1, 60) = ( 1 x 60 ) / 60
GCD(1, 60) = 60 / 60
GCD(1, 60) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 72
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 72) = 72
GCD(1, 72) = ( 1 x 72 ) / 72
GCD(1, 72) = 72 / 72
GCD(1, 72) = 1
GCD of 30, 7, 60, 72 is 1
