Given numbers are 891,563,918,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 891,563,918,441 is 835720578.
Find LCM of 891,563,918,441 with Prime Factorization
| 3 | 891, 563, 918, 441 |
| 3 | 297, 563, 306, 147 |
| 3 | 99, 563, 102, 49 |
| 33, 563, 34, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 33 x 563 x 34 x 49 = 835720578
Therefore, the lowest common multiple of 891,563,918,441 is 835720578.
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 563 x 918 x 441 = 203080100454
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
563 : 1, 563
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,563,918,441, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
563:563
918:2x 3x 3x 3x 17
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3 = 243
Therefore, the value for common factors is 243.
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 = 203080100454/(1x243)
LCM = 203080100454/243
LCM = 835720578
Thus, we can understand that the LCM of 891,563,918,441 is 835720578.
