Given numbers are 860,668,387,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,668,387,920 is 59458680.
Find LCM of 860,668,387,920 with Prime Factorization
| 2 | 860, 668, 387, 920 |
| 2 | 430, 334, 387, 460 |
| 5 | 215, 167, 387, 230 |
| 43 | 43, 167, 387, 46 |
| 1, 167, 9, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 1 x 167 x 9 x 46 = 59458680
Therefore, the lowest common multiple of 860,668,387,920 is 59458680.
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.
860 x 668 x 387 x 920 = 204537859200
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
668 : 1, 2, 4, 167, 334, 668
387 : 1, 3, 9, 43, 129, 387
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,668,387,920, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
668:2x 2x 167
387:3x 3x 43
920:2x 2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 43 = 3440
Therefore, the value for common factors is 3440.
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 = 204537859200/(1x3440)
LCM = 204537859200/3440
LCM = 59458680
Thus, we can understand that the LCM of 860,668,387,920 is 59458680.
