Given numbers are 126,399,490,246
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,399,490,246 is 3435390.
Find LCM of 126,399,490,246 with Prime Factorization
| 2 | 126, 399, 490, 246 |
| 3 | 63, 399, 245, 123 |
| 7 | 21, 133, 245, 41 |
| 3, 19, 35, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 3 x 19 x 35 x 41 = 3435390
Therefore, the lowest common multiple of 126,399,490,246 is 3435390.
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.
126 x 399 x 490 x 246 = 6060027960
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
399 : 1, 3, 7, 19, 21, 57, 133, 399
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
246 : 1, 2, 3, 6, 41, 82, 123, 246
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,399,490,246, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
399:3x 7x 19
490:2x 5x 7x 7
246:2x 3x 41
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 7x 7 = 1764
Therefore, the value for common factors is 1764.
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 = 6060027960/(1x1764)
LCM = 6060027960/1764
LCM = 3435390
Thus, we can understand that the LCM of 126,399,490,246 is 3435390.
