Given numbers are 549,891,505,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,891,505,918 is 933206670.
Find LCM of 549,891,505,918 with Prime Factorization
| 3 | 549, 891, 505, 918 |
| 3 | 183, 297, 505, 306 |
| 3 | 61, 99, 505, 102 |
| 61, 33, 505, 34 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 61 x 33 x 505 x 34 = 933206670
Therefore, the lowest common multiple of 549,891,505,918 is 933206670.
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.
549 x 891 x 505 x 918 = 226769220810
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.
549 : 1, 3, 9, 61, 183, 549
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
505 : 1, 5, 101, 505
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,891,505,918, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
891:3x 3x 3x 3x 11
505:5x 101
918:2x 3x 3x 3x 17
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 = 226769220810/(1x243)
LCM = 226769220810/243
LCM = 933206670
Thus, we can understand that the LCM of 549,891,505,918 is 933206670.
