Given numbers are 246,723,648,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 246,723,648,990 is 352158840.
Find LCM of 246,723,648,990 with Prime Factorization
| 2 | 246, 723, 648, 990 |
| 3 | 123, 723, 324, 495 |
| 3 | 41, 241, 108, 165 |
| 41, 241, 36, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 41 x 241 x 36 x 55 = 352158840
Therefore, the lowest common multiple of 246,723,648,990 is 352158840.
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.
246 x 723 x 648 x 990 = 114099464160
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.
246 : 1, 2, 3, 6, 41, 82, 123, 246
723 : 1, 3, 241, 723
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 246,723,648,990, is 3.
Now, the common factors can be found like this.
246:2x 3x 41
723:3x 241
648:2x 2x 2x 3x 3x 3x 3
990:2x 3x 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 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 = 114099464160/(3x108)
LCM = 114099464160/324
LCM = 352158840
Thus, we can understand that the LCM of 246,723,648,990 is 352158840.
