Make use of GCD Calculator to determine the Greatest Common Divisor of 921, 821, 85, 278 i.e. 1 largest integer that divides all the numbers equally.
GCD of 921, 821, 85, 278 is 1
GCD(921, 821, 85, 278) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 921, 821, 85, 278 is 1
GCD(921, 821, 85, 278) = 1
Given Input numbers are 921, 821, 85, 278
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 139, 278
Greatest Common Divisior
We found the divisors of 921, 821, 85, 278 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 921, 821, 85, 278 is 1.
Therefore, GCD of numbers 921, 821, 85, 278 is 1
Given Input Data is 921, 821, 85, 278
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 921 is 3 x 307
Prime Factorization of 821 is 821
Prime Factorization of 85 is 5 x 17
Prime Factorization of 278 is 2 x 139
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(921, 821) = 756141
GCD(921, 821) = ( 921 x 821 ) / 756141
GCD(921, 821) = 756141 / 756141
GCD(921, 821) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 85) = 85
GCD(1, 85) = ( 1 x 85 ) / 85
GCD(1, 85) = 85 / 85
GCD(1, 85) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 278
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
GCD(1, 278) = 278 / 278
GCD(1, 278) = 1
GCD of 921, 821, 85, 278 is 1
