Given numbers are 261,451,946,292,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,451,946,292,489 is 240910628508.
Find LCM of 261,451,946,292,489 with Prime Factorization
| 2 | 261, 451, 946, 292, 489 |
| 3 | 261, 451, 473, 146, 489 |
| 11 | 87, 451, 473, 146, 163 |
| 87, 41, 43, 146, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 87 x 41 x 43 x 146 x 163 = 240910628508
Therefore, the lowest common multiple of 261,451,946,292,489 is 240910628508.
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.
261 x 451 x 946 x 292 x 489 = 15900101481528
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.
261 : 1, 3, 9, 29, 87, 261
451 : 1, 11, 41, 451
946 : 1, 2, 11, 22, 43, 86, 473, 946
292 : 1, 2, 4, 73, 146, 292
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,451,946,292,489, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
451:11x 41
946:2x 11x 43
292:2x 2x 73
489:3x 163
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 = 15900101481528/(1x66)
LCM = 15900101481528/66
LCM = 240910628508
Thus, we can understand that the LCM of 261,451,946,292,489 is 240910628508.
