GCD of 120, 442, 71, 972 is 1
GCD(120, 442, 71, 972) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 120, 442, 71, 972 is 1
GCD(120, 442, 71, 972) = 1
Given Input numbers are 120, 442, 71, 972
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
Greatest Common Divisior
We found the divisors of 120, 442, 71, 972 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 120, 442, 71, 972 is 1.
Therefore, GCD of numbers 120, 442, 71, 972 is 1
Given Input Data is 120, 442, 71, 972
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5
Prime Factorization of 442 is 2 x 13 x 17
Prime Factorization of 71 is 71
Prime Factorization of 972 is 2 x 2 x 3 x 3 x 3 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(120, 442) = 26520
GCD(120, 442) = ( 120 x 442 ) / 26520
GCD(120, 442) = 53040 / 26520
GCD(120, 442) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 71
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 71) = 142
GCD(2, 71) = ( 2 x 71 ) / 142
GCD(2, 71) = 142 / 142
GCD(2, 71) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 972
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 972) = 972
GCD(1, 972) = ( 1 x 972 ) / 972
GCD(1, 972) = 972 / 972
GCD(1, 972) = 1
GCD of 120, 442, 71, 972 is 1
