Given numbers are 381,136,663,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,136,663,802 is 270116808.
Find LCM of 381,136,663,802 with Prime Factorization
| 2 | 381, 136, 663, 802 |
| 3 | 381, 68, 663, 401 |
| 17 | 127, 68, 221, 401 |
| 127, 4, 13, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 127 x 4 x 13 x 401 = 270116808
Therefore, the lowest common multiple of 381,136,663,802 is 270116808.
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.
381 x 136 x 663 x 802 = 27551914416
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.
381 : 1, 3, 127, 381
136 : 1, 2, 4, 8, 17, 34, 68, 136
663 : 1, 3, 13, 17, 39, 51, 221, 663
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,136,663,802, is 1.
Now, the common factors can be found like this.
381:3x 127
136:2x 2x 2x 17
663:3x 13x 17
802:2x 401
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 = 27551914416/(1x102)
LCM = 27551914416/102
LCM = 270116808
Thus, we can understand that the LCM of 381,136,663,802 is 270116808.
