Given numbers are 709,939,305,860,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,939,305,860,660 is 384178272060.
Find LCM of 709,939,305,860,660 with Prime Factorization
| 2 | 709, 939, 305, 860, 660 |
| 2 | 709, 939, 305, 430, 330 |
| 3 | 709, 939, 305, 215, 165 |
| 5 | 709, 313, 305, 215, 55 |
| 709, 313, 61, 43, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 709 x 313 x 61 x 43 x 11 = 384178272060
Therefore, the lowest common multiple of 709,939,305,860,660 is 384178272060.
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.
709 x 939 x 305 x 860 x 660 = 115253481618000
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.
709 : 1, 709
939 : 1, 3, 313, 939
305 : 1, 5, 61, 305
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,939,305,860,660, is 1.
Now, the common factors can be found like this.
709:709
939:3x 313
305:5x 61
860:2x 2x 5x 43
660:2x 2x 3x 5x 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 2x 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 115253481618000/(1x300)
LCM = 115253481618000/300
LCM = 384178272060
Thus, we can understand that the LCM of 709,939,305,860,660 is 384178272060.
