Given numbers are 143,787,897,391
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,787,897,391 is 132010593.
Find LCM of 143,787,897,391 with Prime Factorization
| 13 | 143, 787, 897, 391 |
| 23 | 11, 787, 69, 391 |
| 11, 787, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 23 x 11 x 787 x 3 x 17 = 132010593
Therefore, the lowest common multiple of 143,787,897,391 is 132010593.
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.
143 x 787 x 897 x 391 = 39471167307
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.
143 : 1, 11, 13, 143
787 : 1, 787
897 : 1, 3, 13, 23, 39, 69, 299, 897
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,787,897,391, is 1.
Now, the common factors can be found like this.
143:11x 13
787:787
897:3x 13x 23
391:17x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 23 = 299
Therefore, the value for common factors is 299.
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 = 39471167307/(1x299)
LCM = 39471167307/299
LCM = 132010593
Thus, we can understand that the LCM of 143,787,897,391 is 132010593.
