Given numbers are 644,806,228,740,895
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 644,806,228,740,895 is 489880924260.
Find LCM of 644,806,228,740,895 with Prime Factorization
| 2 | 644, 806, 228, 740, 895 |
| 2 | 322, 403, 114, 370, 895 |
| 5 | 161, 403, 57, 185, 895 |
| 161, 403, 57, 37, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 161 x 403 x 57 x 37 x 179 = 489880924260
Therefore, the lowest common multiple of 644,806,228,740,895 is 489880924260.
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.
644 x 806 x 228 x 740 x 895 = 78380947881600
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
806 : 1, 2, 13, 26, 31, 62, 403, 806
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
895 : 1, 5, 179, 895
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,806,228,740,895, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
806:2x 13x 31
228:2x 2x 3x 19
740:2x 2x 5x 37
895:5x 179
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 78380947881600/(1x160)
LCM = 78380947881600/160
LCM = 489880924260
Thus, we can understand that the LCM of 644,806,228,740,895 is 489880924260.
