Given numbers are 144,641,969,801,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 144,641,969,801,663 is 34495020144.
Find LCM of 144,641,969,801,663 with Prime Factorization
| 3 | 144, 641, 969, 801, 663 |
| 3 | 48, 641, 323, 267, 221 |
| 17 | 16, 641, 323, 89, 221 |
| 16, 641, 19, 89, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 16 x 641 x 19 x 89 x 13 = 34495020144
Therefore, the lowest common multiple of 144,641,969,801,663 is 34495020144.
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.
144 x 641 x 969 x 801 x 663 = 47499642738288
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
641 : 1, 641
969 : 1, 3, 17, 19, 51, 57, 323, 969
801 : 1, 3, 9, 89, 267, 801
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,641,969,801,663, is 1.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
641:641
969:3x 17x 19
801:3x 3x 89
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 17 = 1377
Therefore, the value for common factors is 1377.
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 = 47499642738288/(1x1377)
LCM = 47499642738288/1377
LCM = 34495020144
Thus, we can understand that the LCM of 144,641,969,801,663 is 34495020144.
