Make use of GCD Calculator to determine the Greatest Common Divisor of 841, 155, 77 i.e. 1 largest integer that divides all the numbers equally.
GCD of 841, 155, 77 is 1
GCD(841, 155, 77) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 841, 155, 77 is 1
GCD(841, 155, 77) = 1
Given Input numbers are 841, 155, 77
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 841

1, 29, 841
Divisors of 155
List of positive integer divisors of 155 that divides 155 without a remainder.
1, 5, 31, 155
Divisors of 77
List of positive integer divisors of 77 that divides 77 without a remainder.
1, 7, 11, 77
Greatest Common Divisior
We found the divisors of 841, 155, 77 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 841, 155, 77 is 1.
Therefore, GCD of numbers 841, 155, 77 is 1
Given Input Data is 841, 155, 77
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 841 is 29 x 29
Prime Factorization of 155 is 5 x 31
Prime Factorization of 77 is 7 x 11
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(841, 155) = 130355
GCD(841, 155) = ( 841 x 155 ) / 130355
GCD(841, 155) = 130355 / 130355
GCD(841, 155) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 77
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 77) = 77
GCD(1, 77) = ( 1 x 77 ) / 77
GCD(1, 77) = 77 / 77
GCD(1, 77) = 1
GCD of 841, 155, 77 is 1
