Make use of GCD Calculator to determine the Greatest Common Divisor of 77, 920, 697, 827 i.e. 1 largest integer that divides all the numbers equally.
GCD of 77, 920, 697, 827 is 1
GCD(77, 920, 697, 827) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 77, 920, 697, 827 is 1
GCD(77, 920, 697, 827) = 1
Given Input numbers are 77, 920, 697, 827
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 77

1, 827
Greatest Common Divisior
We found the divisors of 77, 920, 697, 827 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 77, 920, 697, 827 is 1.
Therefore, GCD of numbers 77, 920, 697, 827 is 1
Given Input Data is 77, 920, 697, 827
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 77 is 7 x 11
Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23
Prime Factorization of 697 is 17 x 41
Prime Factorization of 827 is 827
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(77, 920) = 70840
GCD(77, 920) = ( 77 x 920 ) / 70840
GCD(77, 920) = 70840 / 70840
GCD(77, 920) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 697
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
GCD(1, 697) = 697 / 697
GCD(1, 697) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 827
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 827) = 827
GCD(1, 827) = ( 1 x 827 ) / 827
GCD(1, 827) = 827 / 827
GCD(1, 827) = 1
GCD of 77, 920, 697, 827 is 1
