Given numbers are 999,956,942,438,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 999,956,942,438,987 is 3601154804436.
Find LCM of 999,956,942,438,987 with Prime Factorization
| 2 | 999, 956, 942, 438, 987 |
| 3 | 999, 478, 471, 219, 987 |
| 333, 478, 157, 73, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 333 x 478 x 157 x 73 x 329 = 3601154804436
Therefore, the lowest common multiple of 999,956,942,438,987 is 3601154804436.
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.
999 x 956 x 942 x 438 x 987 = 388924718879088
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.
999 : 1, 3, 9, 27, 37, 111, 333, 999
956 : 1, 2, 4, 239, 478, 956
942 : 1, 2, 3, 6, 157, 314, 471, 942
438 : 1, 2, 3, 6, 73, 146, 219, 438
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 999,956,942,438,987, is 1.
Now, the common factors can be found like this.
999:3x 3x 3x 37
956:2x 2x 239
942:2x 3x 157
438:2x 3x 73
987:3x 7x 47
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 3 = 108
Therefore, the value for common factors is 108.
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 = 388924718879088/(1x108)
LCM = 388924718879088/108
LCM = 3601154804436
Thus, we can understand that the LCM of 999,956,942,438,987 is 3601154804436.
