Given numbers are 891,659,381,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,659,381,609 is 15137803989.
Find LCM of 891,659,381,609 with Prime Factorization
| 3 | 891, 659, 381, 609 |
| 297, 659, 127, 203 |
Multiply the prime numbers at the bottom and the left side.
3 x 297 x 659 x 127 x 203 = 15137803989
Therefore, the lowest common multiple of 891,659,381,609 is 15137803989.
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.
891 x 659 x 381 x 609 = 136240235901
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
659 : 1, 659
381 : 1, 3, 127, 381
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,659,381,609, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
659:659
381:3x 127
609:3x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 136240235901/(1x9)
LCM = 136240235901/9
LCM = 15137803989
Thus, we can understand that the LCM of 891,659,381,609 is 15137803989.
