Given numbers are 442,378,280,709,343
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,378,280,709,343 is 58043873160.
Find LCM of 442,378,280,709,343 with Prime Factorization
| 2 | 442, 378, 280, 709, 343 |
| 7 | 221, 189, 140, 709, 343 |
| 221, 27, 20, 709, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 221 x 27 x 20 x 709 x 49 = 58043873160
Therefore, the lowest common multiple of 442,378,280,709,343 is 58043873160.
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 378 x 280 x 709 x 343 = 11376599139360
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
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
709 : 1, 709
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,378,280,709,343, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
378:2x 3x 3x 3x 7
280:2x 2x 2x 5x 7
709:709
343:7x 7x 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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 11376599139360/(1x196)
LCM = 11376599139360/196
LCM = 58043873160
Thus, we can understand that the LCM of 442,378,280,709,343 is 58043873160.
