Given numbers are 358,715,830
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 358,715,830 is 21245510.
Find LCM of 358,715,830 with Prime Factorization
| 2 | 358, 715, 830 |
| 5 | 179, 715, 415 |
| 179, 143, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 179 x 143 x 83 = 21245510
Therefore, the lowest common multiple of 358,715,830 is 21245510.
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.
358 x 715 x 830 = 212455100
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.
358 : 1, 2, 179, 358
715 : 1, 5, 11, 13, 55, 65, 143, 715
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 358,715,830, is 1.
Now, the common factors can be found like this.
358:2x 179
715:5x 11x 13
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.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 212455100/(1x10)
LCM = 212455100/10
LCM = 21245510
Thus, we can understand that the LCM of 358,715,830 is 21245510.
