Find LCM of 482,676,642,960,640 with Prime Factorization
| 2 | 482, 676, 642, 960, 640 |
| 2 | 241, 338, 321, 480, 320 |
| 2 | 241, 169, 321, 240, 160 |
| 2 | 241, 169, 321, 120, 80 |
| 2 | 241, 169, 321, 60, 40 |
| 2 | 241, 169, 321, 30, 20 |
| 3 | 241, 169, 321, 15, 10 |
| 5 | 241, 169, 107, 5, 10 |
| 241, 169, 107, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 3 x 5 x 241 x 169 x 107 x 1 x 2 = 8367365760
Therefore, the lowest common multiple of 482,676,642,960,640 is 8367365760.
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.
482 x 676 x 642 x 960 x 640 = 128522738073600
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.
482 : 1, 2, 241, 482
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
642 : 1, 2, 3, 6, 107, 214, 321, 642
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 482,676,642,960,640, is 2.
Now, the common factors can be found like this.
482:2x 241
676:2x 2x 13x 13
642:2x 3x 107
960:2x 2x 2x 2x 2x 2x 3x 5
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 2x 2x 2x 2x 2x 3x 5 = 7680
Therefore, the value for common factors is 7680.
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 = 128522738073600/(2x7680)
LCM = 128522738073600/15360
LCM = 8367365760
Thus, we can understand that the LCM of 482,676,642,960,640 is 8367365760.
