Given numbers are 884,617,884,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 884,617,884,690 is 188172660.
Find LCM of 884,617,884,690 with Prime Factorization
| 2 | 884, 617, 884, 690 |
| 2 | 442, 617, 442, 345 |
| 13 | 221, 617, 221, 345 |
| 17 | 17, 617, 17, 345 |
| 1, 617, 1, 345 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 1 x 617 x 1 x 345 = 188172660
Therefore, the lowest common multiple of 884,617,884,690 is 188172660.
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.
884 x 617 x 884 x 690 = 332689262880
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
617 : 1, 617
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,617,884,690, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
617:617
884:2x 2x 13x 17
690:2x 3x 5x 23
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 2x 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 332689262880/(1x1768)
LCM = 332689262880/1768
LCM = 188172660
Thus, we can understand that the LCM of 884,617,884,690 is 188172660.
