Given numbers are 906,641,906,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 906,641,906,819 is 158543658.
Find LCM of 906,641,906,819 with Prime Factorization
| 2 | 906, 641, 906, 819 |
| 3 | 453, 641, 453, 819 |
| 151 | 151, 641, 151, 273 |
| 1, 641, 1, 273 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 1 x 641 x 1 x 273 = 158543658
Therefore, the lowest common multiple of 906,641,906,819 is 158543658.
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.
906 x 641 x 906 x 819 = 430921662444
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
641 : 1, 641
906 : 1, 2, 3, 6, 151, 302, 453, 906
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,641,906,819, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
641:641
906:2x 3x 151
819:3x 3x 7x 13
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 151 = 2718
Therefore, the value for common factors is 2718.
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 = 430921662444/(1x2718)
LCM = 430921662444/2718
LCM = 158543658
Thus, we can understand that the LCM of 906,641,906,819 is 158543658.
