Given numbers are 721,813,998,287,792
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,813,998,287,792 is 3166023539448.
Find LCM of 721,813,998,287,792 with Prime Factorization
| 2 | 721, 813, 998, 287, 792 |
| 3 | 721, 813, 499, 287, 396 |
| 7 | 721, 271, 499, 287, 132 |
| 103, 271, 499, 41, 132 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 103 x 271 x 499 x 41 x 132 = 3166023539448
Therefore, the lowest common multiple of 721,813,998,287,792 is 3166023539448.
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.
721 x 813 x 998 x 287 x 792 = 132972988656816
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.
721 : 1, 7, 103, 721
813 : 1, 3, 271, 813
998 : 1, 2, 499, 998
287 : 1, 7, 41, 287
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,813,998,287,792, is 1.
Now, the common factors can be found like this.
721:7x 103
813:3x 271
998:2x 499
287:7x 41
792:2x 2x 2x 3x 3x 11
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 7 = 42
Therefore, the value for common factors is 42.
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 = 132972988656816/(1x42)
LCM = 132972988656816/42
LCM = 3166023539448
Thus, we can understand that the LCM of 721,813,998,287,792 is 3166023539448.
