Make use of GCD Calculator to determine the Greatest Common Divisor of 428, 904, 91, 302 i.e. 1 largest integer that divides all the numbers equally.
GCD of 428, 904, 91, 302 is 1
GCD(428, 904, 91, 302) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 428, 904, 91, 302 is 1
GCD(428, 904, 91, 302) = 1
Given Input numbers are 428, 904, 91, 302
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 151, 302
Greatest Common Divisior
We found the divisors of 428, 904, 91, 302 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 428, 904, 91, 302 is 1.
Therefore, GCD of numbers 428, 904, 91, 302 is 1
Given Input Data is 428, 904, 91, 302
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 428 is 2 x 2 x 107
Prime Factorization of 904 is 2 x 2 x 2 x 113
Prime Factorization of 91 is 7 x 13
Prime Factorization of 302 is 2 x 151
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(428, 904) = 96728
GCD(428, 904) = ( 428 x 904 ) / 96728
GCD(428, 904) = 386912 / 96728
GCD(428, 904) = 4
Step2:
Here we consider the GCD from the above i.e. 4 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(4, 91) = 364
GCD(4, 91) = ( 4 x 91 ) / 364
GCD(4, 91) = 364 / 364
GCD(4, 91) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 302
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 302) = 302
GCD(1, 302) = ( 1 x 302 ) / 302
GCD(1, 302) = 302 / 302
GCD(1, 302) = 1
GCD of 428, 904, 91, 302 is 1
