Find LCM of 165,986,143,898,690 with Prime Factorization
| 2 | 165, 986, 143, 898, 690 |
| 3 | 165, 493, 143, 449, 345 |
| 5 | 55, 493, 143, 449, 115 |
| 11 | 11, 493, 143, 449, 23 |
| 1, 493, 13, 449, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 1 x 493 x 13 x 449 x 23 = 21841295190
Therefore, the lowest common multiple of 165,986,143,898,690 is 21841295190.
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.
165 x 986 x 143 x 898 x 690 = 14415254825400
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.
165 : 1, 3, 5, 11, 15, 33, 55, 165
986 : 1, 2, 17, 29, 34, 58, 493, 986
143 : 1, 11, 13, 143
898 : 1, 2, 449, 898
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,986,143,898,690, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
986:2x 17x 29
143:11x 13
898:2x 449
690:2x 3x 5x 23
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 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 14415254825400/(1x660)
LCM = 14415254825400/660
LCM = 21841295190
Thus, we can understand that the LCM of 165,986,143,898,690 is 21841295190.
