Given numbers are 705,477,979,240,285
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,477,979,240,285 is 33361265520.
Find LCM of 705,477,979,240,285 with Prime Factorization
| 3 | 705, 477, 979, 240, 285 |
| 5 | 235, 159, 979, 80, 95 |
| 47, 159, 979, 16, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 47 x 159 x 979 x 16 x 19 = 33361265520
Therefore, the lowest common multiple of 705,477,979,240,285 is 33361265520.
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.
705 x 477 x 979 x 240 x 285 = 22518854226000
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
477 : 1, 3, 9, 53, 159, 477
979 : 1, 11, 89, 979
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,477,979,240,285, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
477:3x 3x 53
979:11x 89
240:2x 2x 2x 2x 3x 5
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5 = 675
Therefore, the value for common factors is 675.
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 = 22518854226000/(1x675)
LCM = 22518854226000/675
LCM = 33361265520
Thus, we can understand that the LCM of 705,477,979,240,285 is 33361265520.
