Find LCM of 165,963,638,986 with Prime Factorization
| 2 | 165, 963, 638, 986 |
| 3 | 165, 963, 319, 493 |
| 11 | 55, 321, 319, 493 |
| 29 | 5, 321, 29, 493 |
| 5, 321, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 5 x 321 x 1 x 17 = 52223490
Therefore, the lowest common multiple of 165,963,638,986 is 52223490.
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 963 x 638 x 986 = 99955759860
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
963 : 1, 3, 9, 107, 321, 963
638 : 1, 2, 11, 22, 29, 58, 319, 638
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,963,638,986, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
963:3x 3x 107
638:2x 11x 29
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 29 = 1914
Therefore, the value for common factors is 1914.
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 = 99955759860/(1x1914)
LCM = 99955759860/1914
LCM = 52223490
Thus, we can understand that the LCM of 165,963,638,986 is 52223490.
