Find LCM of 432,840,605,357,271 with Prime Factorization
| 2 | 432, 840, 605, 357, 271 |
| 2 | 216, 420, 605, 357, 271 |
| 2 | 108, 210, 605, 357, 271 |
| 3 | 54, 105, 605, 357, 271 |
| 5 | 18, 35, 605, 119, 271 |
| 7 | 18, 7, 121, 119, 271 |
| 18, 1, 121, 17, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 18 x 1 x 121 x 17 x 271 = 8428598640
Therefore, the lowest common multiple of 432,840,605,357,271 is 8428598640.
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.
432 x 840 x 605 x 357 x 271 = 21240068572800
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
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
605 : 1, 5, 11, 55, 121, 605
357 : 1, 3, 7, 17, 21, 51, 119, 357
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,840,605,357,271, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
840:2x 2x 2x 3x 5x 7
605:5x 11x 11
357:3x 7x 17
271:271
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 3x 3x 5x 7 = 2520
Therefore, the value for common factors is 2520.
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 = 21240068572800/(1x2520)
LCM = 21240068572800/2520
LCM = 8428598640
Thus, we can understand that the LCM of 432,840,605,357,271 is 8428598640.
