Given numbers are 715,918,792,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,918,792,942 is 412200360.
Find LCM of 715,918,792,942 with Prime Factorization
| 2 | 715, 918, 792, 942 |
| 3 | 715, 459, 396, 471 |
| 3 | 715, 153, 132, 157 |
| 11 | 715, 51, 44, 157 |
| 65, 51, 4, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 65 x 51 x 4 x 157 = 412200360
Therefore, the lowest common multiple of 715,918,792,942 is 412200360.
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.
715 x 918 x 792 x 942 = 489694027680
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,918,792,942, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
918:2x 3x 3x 3x 17
792:2x 2x 2x 3x 3x 11
942:2x 3x 157
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 3x 3x 3x 11 = 1188
Therefore, the value for common factors is 1188.
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 = 489694027680/(1x1188)
LCM = 489694027680/1188
LCM = 412200360
Thus, we can understand that the LCM of 715,918,792,942 is 412200360.
