Given numbers are 133,381,342,914,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 133,381,342,914,521 is 72390535686.
Find LCM of 133,381,342,914,521 with Prime Factorization
| 2 | 133, 381, 342, 914, 521 |
| 3 | 133, 381, 171, 457, 521 |
| 19 | 133, 127, 57, 457, 521 |
| 7, 127, 3, 457, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 7 x 127 x 3 x 457 x 521 = 72390535686
Therefore, the lowest common multiple of 133,381,342,914,521 is 72390535686.
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.
133 x 381 x 342 x 914 x 521 = 8252521068204
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.
133 : 1, 7, 19, 133
381 : 1, 3, 127, 381
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
914 : 1, 2, 457, 914
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 133,381,342,914,521, is 1.
Now, the common factors can be found like this.
133:7x 19
381:3x 127
342:2x 3x 3x 19
914:2x 457
521:521
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 19 = 114
Therefore, the value for common factors is 114.
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 = 8252521068204/(1x114)
LCM = 8252521068204/114
LCM = 72390535686
Thus, we can understand that the LCM of 133,381,342,914,521 is 72390535686.
