Given numbers are 684,795,641,442,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,795,641,442,946 is 12145444662780.
Find LCM of 684,795,641,442,946 with Prime Factorization
| 2 | 684, 795, 641, 442, 946 |
| 3 | 342, 795, 641, 221, 473 |
| 114, 265, 641, 221, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 114 x 265 x 641 x 221 x 473 = 12145444662780
Therefore, the lowest common multiple of 684,795,641,442,946 is 12145444662780.
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.
684 x 795 x 641 x 442 x 946 = 145745335953360
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
795 : 1, 3, 5, 15, 53, 159, 265, 795
641 : 1, 641
442 : 1, 2, 13, 17, 26, 34, 221, 442
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,795,641,442,946, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
795:3x 5x 53
641:641
442:2x 13x 17
946:2x 11x 43
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 3 = 12
Therefore, the value for common factors is 12.
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 = 145745335953360/(1x12)
LCM = 145745335953360/12
LCM = 12145444662780
Thus, we can understand that the LCM of 684,795,641,442,946 is 12145444662780.
