Given numbers are 898,230,986,920,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,230,986,920,221 is 2647429720.
Find LCM of 898,230,986,920,221 with Prime Factorization
| 2 | 898, 230, 986, 920, 221 |
| 5 | 449, 115, 493, 460, 221 |
| 17 | 449, 23, 493, 92, 221 |
| 23 | 449, 23, 29, 92, 13 |
| 449, 1, 29, 4, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 23 x 449 x 1 x 29 x 4 x 13 = 2647429720
Therefore, the lowest common multiple of 898,230,986,920,221 is 2647429720.
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.
898 x 230 x 986 x 920 x 221 = 41405800820800
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.
898 : 1, 2, 449, 898
230 : 1, 2, 5, 10, 23, 46, 115, 230
986 : 1, 2, 17, 29, 34, 58, 493, 986
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,230,986,920,221, is 1.
Now, the common factors can be found like this.
898:2x 449
230:2x 5x 23
986:2x 17x 29
920:2x 2x 2x 5x 23
221:13x 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 5x 17x 23 = 15640
Therefore, the value for common factors is 15640.
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 = 41405800820800/(1x15640)
LCM = 41405800820800/15640
LCM = 2647429720
Thus, we can understand that the LCM of 898,230,986,920,221 is 2647429720.
