Given numbers are 218,705,285,470
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,705,285,470 is 2920110.
Find LCM of 218,705,285,470 with Prime Factorization
| 2 | 218, 705, 285, 470 |
| 3 | 109, 705, 285, 235 |
| 5 | 109, 235, 95, 235 |
| 47 | 109, 47, 19, 47 |
| 109, 1, 19, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 109 x 1 x 19 x 1 = 2920110
Therefore, the lowest common multiple of 218,705,285,470 is 2920110.
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.
218 x 705 x 285 x 470 = 20586775500
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.
218 : 1, 2, 109, 218
705 : 1, 3, 5, 15, 47, 141, 235, 705
285 : 1, 3, 5, 15, 19, 57, 95, 285
470 : 1, 2, 5, 10, 47, 94, 235, 470
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,705,285,470, is 1.
Now, the common factors can be found like this.
218:2x 109
705:3x 5x 47
285:3x 5x 19
470:2x 5x 47
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 5x 5x 47 = 7050
Therefore, the value for common factors is 7050.
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 = 20586775500/(1x7050)
LCM = 20586775500/7050
LCM = 2920110
Thus, we can understand that the LCM of 218,705,285,470 is 2920110.
