Given numbers are 442,872,766,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,872,766,986 is 2140452184.
Find LCM of 442,872,766,986 with Prime Factorization
| 2 | 442, 872, 766, 986 |
| 17 | 221, 436, 383, 493 |
| 13, 436, 383, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 13 x 436 x 383 x 29 = 2140452184
Therefore, the lowest common multiple of 442,872,766,986 is 2140452184.
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.
442 x 872 x 766 x 986 = 291101497024
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
872 : 1, 2, 4, 8, 109, 218, 436, 872
766 : 1, 2, 383, 766
986 : 1, 2, 17, 29, 34, 58, 493, 986
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,872,766,986, is 2.
Now, the common factors can be found like this.
442:2x 13x 17
872:2x 2x 2x 109
766:2x 383
986:2x 17x 29
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 17 = 68
Therefore, the value for common factors is 68.
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 = 291101497024/(2x68)
LCM = 291101497024/136
LCM = 2140452184
Thus, we can understand that the LCM of 442,872,766,986 is 2140452184.
