Find LCM of 230,440,261,464,618 with Prime Factorization
| 2 | 230, 440, 261, 464, 618 |
| 2 | 115, 220, 261, 232, 309 |
| 2 | 115, 110, 261, 116, 309 |
| 3 | 115, 55, 261, 58, 309 |
| 5 | 115, 55, 87, 58, 103 |
| 29 | 23, 11, 87, 58, 103 |
| 23, 11, 3, 2, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 29 x 23 x 11 x 3 x 2 x 103 = 544111920
Therefore, the lowest common multiple of 230,440,261,464,618 is 544111920.
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.
230 x 440 x 261 x 464 x 618 = 7574037926400
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.
230 : 1, 2, 5, 10, 23, 46, 115, 230
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
261 : 1, 3, 9, 29, 87, 261
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 230,440,261,464,618, is 1.
Now, the common factors can be found like this.
230:2x 5x 23
440:2x 2x 2x 5x 11
261:3x 3x 29
464:2x 2x 2x 2x 29
618:2x 3x 103
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 2x 2x 3x 5x 29 = 13920
Therefore, the value for common factors is 13920.
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 = 7574037926400/(1x13920)
LCM = 7574037926400/13920
LCM = 544111920
Thus, we can understand that the LCM of 230,440,261,464,618 is 544111920.
