The LCM of 646,588,594,442,415 is 101439358020.
Find LCM of 646,588,594,442,415 with Prime Factorization
| 2 | 646, 588, 594, 442, 415 |
| 3 | 323, 294, 297, 221, 415 |
| 17 | 323, 98, 99, 221, 415 |
| 19, 98, 99, 13, 415 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 98 x 99 x 13 x 415 = 101439358020
Therefore, the lowest common multiple of 646,588,594,442,415 is 101439358020.
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.
646 x 588 x 594 x 442 x 415 = 41387258072160
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
442 : 1, 2, 13, 17, 26, 34, 221, 442
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,588,594,442,415, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
588:2x 2x 3x 7x 7
594:2x 3x 3x 3x 11
442:2x 13x 17
415:5x 83
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 41387258072160/(1x408)
LCM = 41387258072160/408
LCM = 101439358020
Thus, we can understand that the LCM of 646,588,594,442,415 is 101439358020.
