Find LCM of 918,840,328,994,543 with Prime Factorization
| 2 | 918, 840, 328, 994, 543 |
| 2 | 459, 420, 164, 497, 543 |
| 2 | 459, 210, 82, 497, 543 |
| 3 | 459, 105, 41, 497, 543 |
| 7 | 153, 35, 41, 497, 181 |
| 153, 5, 41, 71, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 153 x 5 x 41 x 71 x 181 = 67716031320
Therefore, the lowest common multiple of 918,840,328,994,543 is 67716031320.
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.
918 x 840 x 328 x 994 x 543 = 136515519141120
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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
328 : 1, 2, 4, 8, 41, 82, 164, 328
994 : 1, 2, 7, 14, 71, 142, 497, 994
543 : 1, 3, 181, 543
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,840,328,994,543, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
840:2x 2x 2x 3x 5x 7
328:2x 2x 2x 41
994:2x 7x 71
543:3x 181
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 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 136515519141120/(1x2016)
LCM = 136515519141120/2016
LCM = 67716031320
Thus, we can understand that the LCM of 918,840,328,994,543 is 67716031320.
