Given numbers are 345,439,414,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,439,414,805 is 6361110.
Find LCM of 345,439,414,805 with Prime Factorization
| 3 | 345, 439, 414, 805 |
| 5 | 115, 439, 138, 805 |
| 23 | 23, 439, 138, 161 |
| 1, 439, 6, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 1 x 439 x 6 x 7 = 6361110
Therefore, the lowest common multiple of 345,439,414,805 is 6361110.
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.
345 x 439 x 414 x 805 = 50475407850
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
439 : 1, 439
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,439,414,805, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
439:439
414:2x 3x 3x 23
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23x 23 = 7935
Therefore, the value for common factors is 7935.
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 = 50475407850/(1x7935)
LCM = 50475407850/7935
LCM = 6361110
Thus, we can understand that the LCM of 345,439,414,805 is 6361110.
