Make use of GCD Calculator to determine the Greatest Common Divisor of 870, 991, 49, 207 i.e. 1 largest integer that divides all the numbers equally.
GCD of 870, 991, 49, 207 is 1
GCD(870, 991, 49, 207) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 870, 991, 49, 207 is 1
GCD(870, 991, 49, 207) = 1
Given Input numbers are 870, 991, 49, 207
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 870

1, 3, 9, 23, 69, 207
Greatest Common Divisior
We found the divisors of 870, 991, 49, 207 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 870, 991, 49, 207 is 1.
Therefore, GCD of numbers 870, 991, 49, 207 is 1
Given Input Data is 870, 991, 49, 207
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 870 is 2 x 3 x 5 x 29
Prime Factorization of 991 is 991
Prime Factorization of 49 is 7 x 7
Prime Factorization of 207 is 3 x 3 x 23
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(870, 991) = 862170
GCD(870, 991) = ( 870 x 991 ) / 862170
GCD(870, 991) = 862170 / 862170
GCD(870, 991) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 49
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 49) = 49
GCD(1, 49) = ( 1 x 49 ) / 49
GCD(1, 49) = 49 / 49
GCD(1, 49) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 207
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 207) = 207
GCD(1, 207) = ( 1 x 207 ) / 207
GCD(1, 207) = 207 / 207
GCD(1, 207) = 1
GCD of 870, 991, 49, 207 is 1
