Given numbers are 287,412,663,993,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,412,663,993,210 is 129745002660.
Find LCM of 287,412,663,993,210 with Prime Factorization
| 2 | 287, 412, 663, 993, 210 |
| 3 | 287, 206, 663, 993, 105 |
| 7 | 287, 206, 221, 331, 35 |
| 41, 206, 221, 331, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 206 x 221 x 331 x 5 = 129745002660
Therefore, the lowest common multiple of 287,412,663,993,210 is 129745002660.
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.
287 x 412 x 663 x 993 x 210 = 16347870335160
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.
287 : 1, 7, 41, 287
412 : 1, 2, 4, 103, 206, 412
663 : 1, 3, 13, 17, 39, 51, 221, 663
993 : 1, 3, 331, 993
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,412,663,993,210, is 1.
Now, the common factors can be found like this.
287:7x 41
412:2x 2x 103
663:3x 13x 17
993:3x 331
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 16347870335160/(1x126)
LCM = 16347870335160/126
LCM = 129745002660
Thus, we can understand that the LCM of 287,412,663,993,210 is 129745002660.
