Find LCM of 808,671,147,840,288 with Prime Factorization
| 2 | 808, 671, 147, 840, 288 |
| 2 | 404, 671, 147, 420, 144 |
| 2 | 202, 671, 147, 210, 72 |
| 3 | 101, 671, 147, 105, 36 |
| 7 | 101, 671, 49, 35, 12 |
| 101, 671, 7, 5, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 101 x 671 x 7 x 5 x 12 = 4781921760
Therefore, the lowest common multiple of 808,671,147,840,288 is 4781921760.
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.
808 x 671 x 147 x 840 x 288 = 19280708536320
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
671 : 1, 11, 61, 671
147 : 1, 3, 7, 21, 49, 147
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
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,671,147,840,288, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
671:11x 61
147:3x 7x 7
840:2x 2x 2x 3x 5x 7
288:2x 2x 2x 2x 2x 3x 3
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 3x 3x 7 = 4032
Therefore, the value for common factors is 4032.
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 = 19280708536320/(1x4032)
LCM = 19280708536320/4032
LCM = 4781921760
Thus, we can understand that the LCM of 808,671,147,840,288 is 4781921760.
