Given numbers are 315,990,572,999
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,990,572,999 is 19999980.
Find LCM of 315,990,572,999 with Prime Factorization
| 2 | 315, 990, 572, 999 |
| 3 | 315, 495, 286, 999 |
| 3 | 105, 165, 286, 333 |
| 5 | 35, 55, 286, 111 |
| 11 | 7, 11, 286, 111 |
| 7, 1, 26, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 7 x 1 x 26 x 111 = 19999980
Therefore, the lowest common multiple of 315,990,572,999 is 19999980.
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.
315 x 990 x 572 x 999 = 178199821800
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
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
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
999 : 1, 3, 9, 27, 37, 111, 333, 999
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,990,572,999, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
990:2x 3x 3x 5x 11
572:2x 2x 11x 13
999:3x 3x 3x 37
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 3x 5x 11 = 8910
Therefore, the value for common factors is 8910.
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 = 178199821800/(1x8910)
LCM = 178199821800/8910
LCM = 19999980
Thus, we can understand that the LCM of 315,990,572,999 is 19999980.
