Given numbers are 131,663,848,693,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,663,848,693,646 is 323255748816.
Find LCM of 131,663,848,693,646 with Prime Factorization
| 2 | 131, 663, 848, 693, 646 |
| 3 | 131, 663, 424, 693, 323 |
| 17 | 131, 221, 424, 231, 323 |
| 131, 13, 424, 231, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 131 x 13 x 424 x 231 x 19 = 323255748816
Therefore, the lowest common multiple of 131,663,848,693,646 is 323255748816.
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.
131 x 663 x 848 x 693 x 646 = 32972086379232
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.
131 : 1, 131
663 : 1, 3, 13, 17, 39, 51, 221, 663
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,663,848,693,646, is 1.
Now, the common factors can be found like this.
131:131
663:3x 13x 17
848:2x 2x 2x 2x 53
693:3x 3x 7x 11
646:2x 17x 19
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 17 = 102
Therefore, the value for common factors is 102.
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 = 32972086379232/(1x102)
LCM = 32972086379232/102
LCM = 323255748816
Thus, we can understand that the LCM of 131,663,848,693,646 is 323255748816.
