Given numbers are 381,157,845,444
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,157,845,444 is 7480714020.
Find LCM of 381,157,845,444 with Prime Factorization
| 3 | 381, 157, 845, 444 |
| 127, 157, 845, 148 |
Multiply the prime numbers at the bottom and the left side.
3 x 127 x 157 x 845 x 148 = 7480714020
Therefore, the lowest common multiple of 381,157,845,444 is 7480714020.
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 157 x 845 x 444 = 22442142060
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
157 : 1, 157
845 : 1, 5, 13, 65, 169, 845
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,157,845,444, is 1.
Now, the common factors can be found like this.
381:3x 127
157:157
845:5x 13x 13
444:2x 2x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 22442142060/(1x3)
LCM = 22442142060/3
LCM = 7480714020
Thus, we can understand that the LCM of 381,157,845,444 is 7480714020.
