Find LCM of 110,344,669,520,645 with Prime Factorization
| 2 | 110, 344, 669, 520, 645 |
| 2 | 55, 172, 669, 260, 645 |
| 2 | 55, 86, 669, 130, 645 |
| 3 | 55, 43, 669, 65, 645 |
| 5 | 55, 43, 223, 65, 215 |
| 43 | 11, 43, 223, 13, 43 |
| 11, 1, 223, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 43 x 11 x 1 x 223 x 13 x 1 = 164547240
Therefore, the lowest common multiple of 110,344,669,520,645 is 164547240.
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.
110 x 344 x 669 x 520 x 645 = 8490637584000
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.
110 : 1, 2, 5, 10, 11, 22, 55, 110
344 : 1, 2, 4, 8, 43, 86, 172, 344
669 : 1, 3, 223, 669
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 110,344,669,520,645, is 1.
Now, the common factors can be found like this.
110:2x 5x 11
344:2x 2x 2x 43
669:3x 223
520:2x 2x 2x 5x 13
645:3x 5x 43
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 3x 5x 5x 43 = 51600
Therefore, the value for common factors is 51600.
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 = 8490637584000/(1x51600)
LCM = 8490637584000/51600
LCM = 164547240
Thus, we can understand that the LCM of 110,344,669,520,645 is 164547240.
