The LCM of 894,990,390,858 is 1917630.
Find LCM of 894,990,390,858 with Prime Factorization
| 2 | 894, 990, 390, 858 |
| 3 | 447, 495, 195, 429 |
| 5 | 149, 165, 65, 143 |
| 11 | 149, 33, 13, 143 |
| 13 | 149, 3, 13, 13 |
| 149, 3, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 149 x 3 x 1 x 1 = 1917630
Therefore, the lowest common multiple of 894,990,390,858 is 1917630.
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.
894 x 990 x 390 x 858 = 296158777200
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.
894 : 1, 2, 3, 6, 149, 298, 447, 894
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 894,990,390,858, is 6.
Now, the common factors can be found like this.
894:2x 3x 149
990:2x 3x 3x 5x 11
390:2x 3x 5x 13
858:2x 3x 11x 13
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 5x 11x 13 = 25740
Therefore, the value for common factors is 25740.
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 = 296158777200/(6x25740)
LCM = 296158777200/154440
LCM = 1917630
Thus, we can understand that the LCM of 894,990,390,858 is 1917630.
