Given numbers are 687,886,909,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,886,909,919 is 169491763674.
Find LCM of 687,886,909,919 with Prime Factorization
3 | 687, 886, 909, 919 |
229, 886, 303, 919 |
Multiply the prime numbers at the bottom and the left side.
3 x 229 x 886 x 303 x 919 = 169491763674
Therefore, the lowest common multiple of 687,886,909,919 is 169491763674.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
687 x 886 x 909 x 919 = 508475291022
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
687 : 1, 3, 229, 687
886 : 1, 2, 443, 886
909 : 1, 3, 9, 101, 303, 909
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,886,909,919, is 1.
Now, the common factors can be found like this.
687:3x 229
886:2x 443
909:3x 3x 101
919:919
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 508475291022/(1x3)
LCM = 508475291022/3
LCM = 169491763674
Thus, we can understand that the LCM of 687,886,909,919 is 169491763674.
Here are some samples of LCM of two or more Numbers calculations.
