Given numbers are 990,449,473,104,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,449,473,104,681 is 225620829720.
Find LCM of 990,449,473,104,681 with Prime Factorization
| 2 | 990, 449, 473, 104, 681 |
| 3 | 495, 449, 473, 52, 681 |
| 11 | 165, 449, 473, 52, 227 |
| 15, 449, 43, 52, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 15 x 449 x 43 x 52 x 227 = 225620829720
Therefore, the lowest common multiple of 990,449,473,104,681 is 225620829720.
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.
990 x 449 x 473 x 104 x 681 = 14890974761520
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.
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
449 : 1, 449
473 : 1, 11, 43, 473
104 : 1, 2, 4, 8, 13, 26, 52, 104
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,449,473,104,681, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
449:449
473:11x 43
104:2x 2x 2x 13
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 14890974761520/(1x66)
LCM = 14890974761520/66
LCM = 225620829720
Thus, we can understand that the LCM of 990,449,473,104,681 is 225620829720.
