Find LCM of 183,396,920,424,840 with Prime Factorization
| 2 | 183, 396, 920, 424, 840 |
| 2 | 183, 198, 460, 212, 420 |
| 2 | 183, 99, 230, 106, 210 |
| 3 | 183, 99, 115, 53, 105 |
| 5 | 61, 33, 115, 53, 35 |
| 61, 33, 23, 53, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 61 x 33 x 23 x 53 x 7 = 2061231480
Therefore, the lowest common multiple of 183,396,920,424,840 is 2061231480.
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.
183 x 396 x 920 x 424 x 840 = 23745386649600
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.
183 : 1, 3, 61, 183
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
424 : 1, 2, 4, 8, 53, 106, 212, 424
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 183,396,920,424,840, is 1.
Now, the common factors can be found like this.
183:3x 61
396:2x 2x 3x 3x 11
920:2x 2x 2x 5x 23
424:2x 2x 2x 53
840:2x 2x 2x 3x 5x 7
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 2x 2x 2x 2x 2x 2x 3x 3x 5 = 11520
Therefore, the value for common factors is 11520.
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 = 23745386649600/(1x11520)
LCM = 23745386649600/11520
LCM = 2061231480
Thus, we can understand that the LCM of 183,396,920,424,840 is 2061231480.
