Find LCM of 858,442,448,560 with Prime Factorization
| 2 | 858, 442, 448, 560 |
| 2 | 429, 221, 224, 280 |
| 2 | 429, 221, 112, 140 |
| 2 | 429, 221, 56, 70 |
| 7 | 429, 221, 28, 35 |
| 13 | 429, 221, 4, 5 |
| 33, 17, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 13 x 33 x 17 x 4 x 5 = 16336320
Therefore, the lowest common multiple of 858,442,448,560 is 16336320.
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.
858 x 442 x 448 x 560 = 95142727680
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
442 : 1, 2, 13, 17, 26, 34, 221, 442
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,442,448,560, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
442:2x 13x 17
448:2x 2x 2x 2x 2x 2x 7
560:2x 2x 2x 2x 5x 7
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 = 95142727680/(2x2912)
LCM = 95142727680/5824
LCM = 16336320
Thus, we can understand that the LCM of 858,442,448,560 is 16336320.
