Given numbers are 8,442,742,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 8,442,742,442 is 655928.
Find LCM of 8,442,742,442 with Prime Factorization
| 2 | 8, 442, 742, 442 |
| 13 | 4, 221, 371, 221 |
| 17 | 4, 17, 371, 17 |
| 4, 1, 371, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 4 x 1 x 371 x 1 = 655928
Therefore, the lowest common multiple of 8,442,742,442 is 655928.
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.
8 x 442 x 742 x 442 = 1159680704
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.
8 : 1, 2, 4, 8
442 : 1, 2, 13, 17, 26, 34, 221, 442
742 : 1, 2, 7, 14, 53, 106, 371, 742
442 : 1, 2, 13, 17, 26, 34, 221, 442
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8,442,742,442, is 2.
Now, the common factors can be found like this.
8:2x 2x 2
442:2x 13x 17
742:2x 7x 53
442:2x 13x 17
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 13x 17 = 884
Therefore, the value for common factors is 884.
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 = 1159680704/(2x884)
LCM = 1159680704/1768
LCM = 655928
Thus, we can understand that the LCM of 8,442,742,442 is 655928.
