Given numbers are 280,447,447,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,447,447,278 is 17397240.
Find LCM of 280,447,447,278 with Prime Factorization
| 2 | 280, 447, 447, 278 |
| 3 | 140, 447, 447, 139 |
| 149 | 140, 149, 149, 139 |
| 140, 1, 1, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 140 x 1 x 1 x 139 = 17397240
Therefore, the lowest common multiple of 280,447,447,278 is 17397240.
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.
280 x 447 x 447 x 278 = 15553132560
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
447 : 1, 3, 149, 447
447 : 1, 3, 149, 447
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,447,447,278, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
447:3x 149
447:3x 149
278:2x 139
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 149 = 894
Therefore, the value for common factors is 894.
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 = 15553132560/(1x894)
LCM = 15553132560/894
LCM = 17397240
Thus, we can understand that the LCM of 280,447,447,278 is 17397240.
