Given numbers are 321,605,110,473,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,605,110,473,442 is 3691060230.
Find LCM of 321,605,110,473,442 with Prime Factorization
| 2 | 321, 605, 110, 473, 442 |
| 5 | 321, 605, 55, 473, 221 |
| 11 | 321, 121, 11, 473, 221 |
| 321, 1, 11, 43, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 321 x 1 x 11 x 43 x 221 = 3691060230
Therefore, the lowest common multiple of 321,605,110,473,442 is 3691060230.
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.
321 x 605 x 110 x 473 x 442 = 4466182878300
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.
321 : 1, 3, 107, 321
605 : 1, 5, 11, 55, 121, 605
110 : 1, 2, 5, 10, 11, 22, 55, 110
473 : 1, 11, 43, 473
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,605,110,473,442, is 1.
Now, the common factors can be found like this.
321:3x 107
605:5x 11x 11
110:2x 5x 11
473:11x 43
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 5x 11x 11 = 1210
Therefore, the value for common factors is 1210.
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 = 4466182878300/(1x1210)
LCM = 4466182878300/1210
LCM = 3691060230
Thus, we can understand that the LCM of 321,605,110,473,442 is 3691060230.
