Make use of GCD Calculator to determine the Greatest Common Divisor of 621, 362, 45, 162 i.e. 1 largest integer that divides all the numbers equally.
GCD of 621, 362, 45, 162 is 1
GCD(621, 362, 45, 162) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 621, 362, 45, 162 is 1
GCD(621, 362, 45, 162) = 1
Given Input numbers are 621, 362, 45, 162
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 6, 9, 18, 27, 54, 81, 162
Greatest Common Divisior
We found the divisors of 621, 362, 45, 162 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 621, 362, 45, 162 is 1.
Therefore, GCD of numbers 621, 362, 45, 162 is 1
Given Input Data is 621, 362, 45, 162
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 362 is 2 x 181
Prime Factorization of 45 is 3 x 3 x 5
Prime Factorization of 162 is 2 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(621, 362) = 224802
GCD(621, 362) = ( 621 x 362 ) / 224802
GCD(621, 362) = 224802 / 224802
GCD(621, 362) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 45
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
GCD(1, 45) = 45 / 45
GCD(1, 45) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 162
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
GCD(1, 162) = 162 / 162
GCD(1, 162) = 1
GCD of 621, 362, 45, 162 is 1
