Make use of GCD Calculator to determine the Greatest Common Divisor of 649, 700, 870 i.e. 1 largest integer that divides all the numbers equally.
GCD of 649, 700, 870 is 1
GCD(649, 700, 870) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 649, 700, 870 is 1
GCD(649, 700, 870) = 1
Given Input numbers are 649, 700, 870
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 649

1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
Greatest Common Divisior
We found the divisors of 649, 700, 870 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 649, 700, 870 is 1.
Therefore, GCD of numbers 649, 700, 870 is 1
Given Input Data is 649, 700, 870
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 649 is 11 x 59
Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7
Prime Factorization of 870 is 2 x 3 x 5 x 29
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(649, 700) = 454300
GCD(649, 700) = ( 649 x 700 ) / 454300
GCD(649, 700) = 454300 / 454300
GCD(649, 700) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 870
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
GCD(1, 870) = 870 / 870
GCD(1, 870) = 1
GCD of 649, 700, 870 is 1
