Given numbers are 279,986,558,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,986,558,540 is 8252820.
Find LCM of 279,986,558,540 with Prime Factorization
| 2 | 279, 986, 558, 540 |
| 3 | 279, 493, 279, 270 |
| 3 | 93, 493, 93, 90 |
| 31 | 31, 493, 31, 30 |
| 1, 493, 1, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 31 x 1 x 493 x 1 x 30 = 8252820
Therefore, the lowest common multiple of 279,986,558,540 is 8252820.
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.
279 x 986 x 558 x 540 = 82891324080
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.
279 : 1, 3, 9, 31, 93, 279
986 : 1, 2, 17, 29, 34, 58, 493, 986
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,986,558,540, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
986:2x 17x 29
558:2x 3x 3x 31
540:2x 2x 3x 3x 3x 5
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 3x 3x 3x 31 = 10044
Therefore, the value for common factors is 10044.
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 = 82891324080/(1x10044)
LCM = 82891324080/10044
LCM = 8252820
Thus, we can understand that the LCM of 279,986,558,540 is 8252820.
