Find LCM of 543,826,420,354 with Prime Factorization
| 2 | 543, 826, 420, 354 |
| 3 | 543, 413, 210, 177 |
| 7 | 181, 413, 70, 59 |
| 59 | 181, 59, 10, 59 |
| 181, 1, 10, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 59 x 181 x 1 x 10 x 1 = 4485180
Therefore, the lowest common multiple of 543,826,420,354 is 4485180.
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.
543 x 826 x 420 x 354 = 66685656240
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.
543 : 1, 3, 181, 543
826 : 1, 2, 7, 14, 59, 118, 413, 826
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,826,420,354, is 1.
Now, the common factors can be found like this.
543:3x 181
826:2x 7x 59
420:2x 2x 3x 5x 7
354:2x 3x 59
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 7x 59 = 14868
Therefore, the value for common factors is 14868.
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 = 66685656240/(1x14868)
LCM = 66685656240/14868
LCM = 4485180
Thus, we can understand that the LCM of 543,826,420,354 is 4485180.
