Find LCM of 805,694,345,484,242 with Prime Factorization
| 2 | 805, 694, 345, 484, 242 |
| 5 | 805, 347, 345, 242, 121 |
| 11 | 161, 347, 69, 242, 121 |
| 11 | 161, 347, 69, 22, 11 |
| 23 | 161, 347, 69, 2, 1 |
| 7, 347, 3, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 11 x 23 x 7 x 347 x 3 x 2 x 1 = 405594420
Therefore, the lowest common multiple of 805,694,345,484,242 is 405594420.
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.
805 x 694 x 345 x 484 x 242 = 22575385417200
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
694 : 1, 2, 347, 694
345 : 1, 3, 5, 15, 23, 69, 115, 345
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,694,345,484,242, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
694:2x 347
345:3x 5x 23
484:2x 2x 11x 11
242:2x 11x 11
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 5x 11x 11x 23 = 55660
Therefore, the value for common factors is 55660.
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 = 22575385417200/(1x55660)
LCM = 22575385417200/55660
LCM = 405594420
Thus, we can understand that the LCM of 805,694,345,484,242 is 405594420.
