Given numbers are 261,150,705,391,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,150,705,391,460 is 479639700.
Find LCM of 261,150,705,391,460 with Prime Factorization
| 2 | 261, 150, 705, 391, 460 |
| 3 | 261, 75, 705, 391, 230 |
| 5 | 87, 25, 235, 391, 230 |
| 23 | 87, 5, 47, 391, 46 |
| 87, 5, 47, 17, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 87 x 5 x 47 x 17 x 2 = 479639700
Therefore, the lowest common multiple of 261,150,705,391,460 is 479639700.
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 150 x 705 x 391 x 460 = 4964270895000
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
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
705 : 1, 3, 5, 15, 47, 141, 235, 705
391 : 1, 17, 23, 391
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,150,705,391,460, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
150:2x 3x 5x 5
705:3x 5x 47
391:17x 23
460:2x 2x 5x 23
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 3x 5x 5x 23 = 10350
Therefore, the value for common factors is 10350.
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 = 4964270895000/(1x10350)
LCM = 4964270895000/10350
LCM = 479639700
Thus, we can understand that the LCM of 261,150,705,391,460 is 479639700.
