The LCM of 990,363,450,415 is 4519350.
Find LCM of 990,363,450,415 with Prime Factorization
| 2 | 990, 363, 450, 415 |
| 3 | 495, 363, 225, 415 |
| 3 | 165, 121, 75, 415 |
| 5 | 55, 121, 25, 415 |
| 11 | 11, 121, 5, 83 |
| 1, 11, 5, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 1 x 11 x 5 x 83 = 4519350
Therefore, the lowest common multiple of 990,363,450,415 is 4519350.
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.
990 x 363 x 450 x 415 = 67112347500
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.
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
363 : 1, 3, 11, 33, 121, 363
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,363,450,415, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
363:3x 11x 11
450:2x 3x 3x 5x 5
415:5x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 67112347500/(1x14850)
LCM = 67112347500/14850
LCM = 4519350
Thus, we can understand that the LCM of 990,363,450,415 is 4519350.
