Given numbers are 127,999,489,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 127,999,489,640 is 13235391360.
Find LCM of 127,999,489,640 with Prime Factorization
| 3 | 127, 999, 489, 640 |
| 127, 333, 163, 640 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 333 x 163 x 640 = 13235391360
Therefore, the lowest common multiple of 127,999,489,640 is 13235391360.
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.
127 x 999 x 489 x 640 = 39706174080
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.
127 : 1, 127
999 : 1, 3, 9, 27, 37, 111, 333, 999
489 : 1, 3, 163, 489
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 127,999,489,640, is 1.
Now, the common factors can be found like this.
127:127
999:3x 3x 3x 37
489:3x 163
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 39706174080/(1x3)
LCM = 39706174080/3
LCM = 13235391360
Thus, we can understand that the LCM of 127,999,489,640 is 13235391360.
