Given numbers are 351,249,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,249,830 is 291330.
Find LCM of 351,249,830 with Prime Factorization
| 3 | 351, 249, 830 |
| 83 | 117, 83, 830 |
| 117, 1, 10 |
Multiply the prime numbers at the bottom and the left side.
3 x 83 x 117 x 1 x 10 = 291330
Therefore, the lowest common multiple of 351,249,830 is 291330.
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.
351 x 249 x 830 = 72541170
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
249 : 1, 3, 83, 249
830 : 1, 2, 5, 10, 83, 166, 415, 830
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,249,830, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
249:3x 83
830:2x 5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 83 = 249
Therefore, the value for common factors is 249.
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 = 72541170/(1x249)
LCM = 72541170/249
LCM = 291330
Thus, we can understand that the LCM of 351,249,830 is 291330.
