Make use of GCD Calculator to determine the Greatest Common Divisor of 291, 665, 65, 402 i.e. 1 largest integer that divides all the numbers equally.
GCD of 291, 665, 65, 402 is 1
GCD(291, 665, 65, 402) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 291, 665, 65, 402 is 1
GCD(291, 665, 65, 402) = 1
Given Input numbers are 291, 665, 65, 402
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 6, 67, 134, 201, 402
Greatest Common Divisior
We found the divisors of 291, 665, 65, 402 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 291, 665, 65, 402 is 1.
Therefore, GCD of numbers 291, 665, 65, 402 is 1
Given Input Data is 291, 665, 65, 402
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 291 is 3 x 97
Prime Factorization of 665 is 5 x 7 x 19
Prime Factorization of 65 is 5 x 13
Prime Factorization of 402 is 2 x 3 x 67
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(291, 665) = 193515
GCD(291, 665) = ( 291 x 665 ) / 193515
GCD(291, 665) = 193515 / 193515
GCD(291, 665) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 402
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
GCD(1, 402) = 402 / 402
GCD(1, 402) = 1
GCD of 291, 665, 65, 402 is 1
