Given numbers are 621,906,820,938,826
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,906,820,938,826 is 2127684619620.
Find LCM of 621,906,820,938,826 with Prime Factorization
| 2 | 621, 906, 820, 938, 826 |
| 3 | 621, 453, 410, 469, 413 |
| 7 | 207, 151, 410, 469, 413 |
| 207, 151, 410, 67, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 207 x 151 x 410 x 67 x 59 = 2127684619620
Therefore, the lowest common multiple of 621,906,820,938,826 is 2127684619620.
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.
621 x 906 x 820 x 938 x 826 = 357451016096160
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
906 : 1, 2, 3, 6, 151, 302, 453, 906
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
938 : 1, 2, 7, 14, 67, 134, 469, 938
826 : 1, 2, 7, 14, 59, 118, 413, 826
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,906,820,938,826, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
906:2x 3x 151
820:2x 2x 5x 41
938:2x 7x 67
826:2x 7x 59
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 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 357451016096160/(1x168)
LCM = 357451016096160/168
LCM = 2127684619620
Thus, we can understand that the LCM of 621,906,820,938,826 is 2127684619620.
