Given numbers are 6870,5379
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 6870,5379 is 12317910.
Find LCM of 6870,5379 with Prime Factorization
| 3 | 6870, 5379 |
| 2290, 1793 |
Multiply the prime numbers at the bottom and the left side.
3 x 2290 x 1793 = 12317910
Therefore, the lowest common multiple of 6870,5379 is 12317910.
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.
6870 x 5379 = 36953730
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.
6870 : 1, 2, 3, 5, 6, 10, 15, 30, 229, 458, 687, 1145, 1374, 2290, 3435, 6870
5379 : 1, 3, 11, 33, 163, 489, 1793, 5379
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6870,5379, is 3.
Now, the common factors can be found like this.
6870:2x 3x 5x 229
5379:3x 11x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 36953730/(3x1)
LCM = 36953730/3
LCM = 12317910
Thus, we can understand that the LCM of 6870,5379 is 12317910.
