Given numbers are 844,107,660,902,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,107,660,902,390 is 7942137060.
Find LCM of 844,107,660,902,390 with Prime Factorization
| 2 | 844, 107, 660, 902, 390 |
| 2 | 422, 107, 330, 451, 195 |
| 3 | 211, 107, 165, 451, 195 |
| 5 | 211, 107, 55, 451, 65 |
| 11 | 211, 107, 11, 451, 13 |
| 211, 107, 1, 41, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 211 x 107 x 1 x 41 x 13 = 7942137060
Therefore, the lowest common multiple of 844,107,660,902,390 is 7942137060.
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.
844 x 107 x 660 x 902 x 390 = 20967241838400
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.
844 : 1, 2, 4, 211, 422, 844
107 : 1, 107
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
902 : 1, 2, 11, 22, 41, 82, 451, 902
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,107,660,902,390, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
107:107
660:2x 2x 3x 5x 11
902:2x 11x 41
390:2x 3x 5x 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 2x 2x 2x 3x 5x 11 = 2640
Therefore, the value for common factors is 2640.
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 = 20967241838400/(1x2640)
LCM = 20967241838400/2640
LCM = 7942137060
Thus, we can understand that the LCM of 844,107,660,902,390 is 7942137060.
