Given numbers are 582,490,646,868,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 582,490,646,868,442 is 37121595420.
Find LCM of 582,490,646,868,442 with Prime Factorization
| 2 | 582, 490, 646, 868, 442 |
| 7 | 291, 245, 323, 434, 221 |
| 17 | 291, 35, 323, 62, 221 |
| 291, 35, 19, 62, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 291 x 35 x 19 x 62 x 13 = 37121595420
Therefore, the lowest common multiple of 582,490,646,868,442 is 37121595420.
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.
582 x 490 x 646 x 868 x 442 = 70679517679680
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.
582 : 1, 2, 3, 6, 97, 194, 291, 582
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
646 : 1, 2, 17, 19, 34, 38, 323, 646
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
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 582,490,646,868,442, is 2.
Now, the common factors can be found like this.
582:2x 3x 97
490:2x 5x 7x 7
646:2x 17x 19
868:2x 2x 7x 31
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 2x 7x 17 = 952
Therefore, the value for common factors is 952.
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 = 70679517679680/(2x952)
LCM = 70679517679680/1904
LCM = 37121595420
Thus, we can understand that the LCM of 582,490,646,868,442 is 37121595420.
