Given numbers are 240,663,478,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,663,478,663 is 12676560.
Find LCM of 240,663,478,663 with Prime Factorization
| 2 | 240, 663, 478, 663 |
| 3 | 120, 663, 239, 663 |
| 13 | 40, 221, 239, 221 |
| 17 | 40, 17, 239, 17 |
| 40, 1, 239, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 40 x 1 x 239 x 1 = 12676560
Therefore, the lowest common multiple of 240,663,478,663 is 12676560.
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.
240 x 663 x 478 x 663 = 50427355680
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
663 : 1, 3, 13, 17, 39, 51, 221, 663
478 : 1, 2, 239, 478
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,663,478,663, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
663:3x 13x 17
478:2x 239
663:3x 13x 17
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 13x 17 = 3978
Therefore, the value for common factors is 3978.
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 = 50427355680/(1x3978)
LCM = 50427355680/3978
LCM = 12676560
Thus, we can understand that the LCM of 240,663,478,663 is 12676560.
