Given numbers are 489,755,305,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,755,305,743 is 16733024985.
Find LCM of 489,755,305,743 with Prime Factorization
| 5 | 489, 755, 305, 743 |
| 489, 151, 61, 743 |
Multiply the prime numbers at the bottom and the left side.
5 x 489 x 151 x 61 x 743 = 16733024985
Therefore, the lowest common multiple of 489,755,305,743 is 16733024985.
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.
489 x 755 x 305 x 743 = 83665124925
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.
489 : 1, 3, 163, 489
755 : 1, 5, 151, 755
305 : 1, 5, 61, 305
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,755,305,743, is 1.
Now, the common factors can be found like this.
489:3x 163
755:5x 151
305:5x 61
743:743
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 83665124925/(1x5)
LCM = 83665124925/5
LCM = 16733024985
Thus, we can understand that the LCM of 489,755,305,743 is 16733024985.
