Given numbers are 866,153,442,121,418
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 866,153,442,121,418 is 3959967726.
Find LCM of 866,153,442,121,418 with Prime Factorization
| 2 | 866, 153, 442, 121, 418 |
| 11 | 433, 153, 221, 121, 209 |
| 17 | 433, 153, 221, 11, 19 |
| 433, 9, 13, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 433 x 9 x 13 x 11 x 19 = 3959967726
Therefore, the lowest common multiple of 866,153,442,121,418 is 3959967726.
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.
866 x 153 x 442 x 121 x 418 = 2962055859048
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.
866 : 1, 2, 433, 866
153 : 1, 3, 9, 17, 51, 153
442 : 1, 2, 13, 17, 26, 34, 221, 442
121 : 1, 11, 121
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 866,153,442,121,418, is 1.
Now, the common factors can be found like this.
866:2x 433
153:3x 3x 17
442:2x 13x 17
121:11x 11
418:2x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 17 = 748
Therefore, the value for common factors is 748.
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 = 2962055859048/(1x748)
LCM = 2962055859048/748
LCM = 3959967726
Thus, we can understand that the LCM of 866,153,442,121,418 is 3959967726.
