Find LCM of 518,576,442,728,431 with Prime Factorization
| 2 | 518, 576, 442, 728, 431 |
| 2 | 259, 288, 221, 364, 431 |
| 2 | 259, 144, 221, 182, 431 |
| 7 | 259, 72, 221, 91, 431 |
| 13 | 37, 72, 221, 13, 431 |
| 37, 72, 17, 1, 431 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 13 x 37 x 72 x 17 x 1 x 431 = 14209925184
Therefore, the lowest common multiple of 518,576,442,728,431 is 14209925184.
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.
518 x 576 x 442 x 728 x 431 = 41379302135808
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
442 : 1, 2, 13, 17, 26, 34, 221, 442
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,576,442,728,431, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
576:2x 2x 2x 2x 2x 2x 3x 3
442:2x 13x 17
728:2x 2x 2x 7x 13
431:431
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 7x 13 = 2912
Therefore, the value for common factors is 2912.
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 = 41379302135808/(1x2912)
LCM = 41379302135808/2912
LCM = 14209925184
Thus, we can understand that the LCM of 518,576,442,728,431 is 14209925184.
