Given numbers are 348,805,858,515,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 348,805,858,515,942 is 647810583420.
Find LCM of 348,805,858,515,942 with Prime Factorization
| 2 | 348, 805, 858, 515, 942 |
| 3 | 174, 805, 429, 515, 471 |
| 5 | 58, 805, 143, 515, 157 |
| 58, 161, 143, 103, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 58 x 161 x 143 x 103 x 157 = 647810583420
Therefore, the lowest common multiple of 348,805,858,515,942 is 647810583420.
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.
348 x 805 x 858 x 515 x 942 = 116605905015600
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.
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
805 : 1, 5, 7, 23, 35, 115, 161, 805
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
515 : 1, 5, 103, 515
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 348,805,858,515,942, is 1.
Now, the common factors can be found like this.
348:2x 2x 3x 29
805:5x 7x 23
858:2x 3x 11x 13
515:5x 103
942:2x 3x 157
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 116605905015600/(1x180)
LCM = 116605905015600/180
LCM = 647810583420
Thus, we can understand that the LCM of 348,805,858,515,942 is 647810583420.
