Given numbers are 442,209,726,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,209,726,605 is 15242370.
Find LCM of 442,209,726,605 with Prime Factorization
| 2 | 442, 209, 726, 605 |
| 11 | 221, 209, 363, 605 |
| 11 | 221, 19, 33, 55 |
| 221, 19, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 221 x 19 x 3 x 5 = 15242370
Therefore, the lowest common multiple of 442,209,726,605 is 15242370.
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 209 x 726 x 605 = 40575188940
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
209 : 1, 11, 19, 209
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,209,726,605, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
209:11x 19
726:2x 3x 11x 11
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 11 = 2662
Therefore, the value for common factors is 2662.
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 = 40575188940/(1x2662)
LCM = 40575188940/2662
LCM = 15242370
Thus, we can understand that the LCM of 442,209,726,605 is 15242370.
