Given numbers are 414,160,690,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 414,160,690,781 is 25866720.
Find LCM of 414,160,690,781 with Prime Factorization
| 2 | 414, 160, 690, 781 |
| 3 | 207, 80, 345, 781 |
| 5 | 69, 80, 115, 781 |
| 23 | 69, 16, 23, 781 |
| 3, 16, 1, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 3 x 16 x 1 x 781 = 25866720
Therefore, the lowest common multiple of 414,160,690,781 is 25866720.
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.
414 x 160 x 690 x 781 = 35696073600
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.
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,160,690,781, is 1.
Now, the common factors can be found like this.
414:2x 3x 3x 23
160:2x 2x 2x 2x 2x 5
690:2x 3x 5x 23
781:11x 71
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 5x 23 = 1380
Therefore, the value for common factors is 1380.
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 = 35696073600/(1x1380)
LCM = 35696073600/1380
LCM = 25866720
Thus, we can understand that the LCM of 414,160,690,781 is 25866720.
