Given numbers are 915,211,858,442,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 915,211,858,442,356 is 167085401340.
Find LCM of 915,211,858,442,356 with Prime Factorization
| 2 | 915, 211, 858, 442, 356 |
| 3 | 915, 211, 429, 221, 178 |
| 13 | 305, 211, 143, 221, 178 |
| 305, 211, 11, 17, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 305 x 211 x 11 x 17 x 178 = 167085401340
Therefore, the lowest common multiple of 915,211,858,442,356 is 167085401340.
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.
915 x 211 x 858 x 442 x 356 = 26065322609040
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.
915 : 1, 3, 5, 15, 61, 183, 305, 915
211 : 1, 211
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
442 : 1, 2, 13, 17, 26, 34, 221, 442
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 915,211,858,442,356, is 1.
Now, the common factors can be found like this.
915:3x 5x 61
211:211
858:2x 3x 11x 13
442:2x 13x 17
356:2x 2x 89
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 26065322609040/(1x156)
LCM = 26065322609040/156
LCM = 167085401340
Thus, we can understand that the LCM of 915,211,858,442,356 is 167085401340.
