Given numbers are 282,330,778,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 282,330,778,385 is 42233730.
Find LCM of 282,330,778,385 with Prime Factorization
| 2 | 282, 330, 778, 385 |
| 3 | 141, 165, 389, 385 |
| 5 | 47, 55, 389, 385 |
| 11 | 47, 11, 389, 77 |
| 47, 1, 389, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 47 x 1 x 389 x 7 = 42233730
Therefore, the lowest common multiple of 282,330,778,385 is 42233730.
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.
282 x 330 x 778 x 385 = 27874261800
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.
282 : 1, 2, 3, 6, 47, 94, 141, 282
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
778 : 1, 2, 389, 778
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,330,778,385, is 1.
Now, the common factors can be found like this.
282:2x 3x 47
330:2x 3x 5x 11
778:2x 389
385:5x 7x 11
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 27874261800/(1x660)
LCM = 27874261800/660
LCM = 42233730
Thus, we can understand that the LCM of 282,330,778,385 is 42233730.
