Given numbers are 989,488,910,620,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,488,910,620,305 is 6807524360.
Find LCM of 989,488,910,620,305 with Prime Factorization
| 2 | 989, 488, 910, 620, 305 |
| 2 | 989, 244, 455, 310, 305 |
| 5 | 989, 122, 455, 155, 305 |
| 61 | 989, 122, 91, 31, 61 |
| 989, 2, 91, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 61 x 989 x 2 x 91 x 31 x 1 = 6807524360
Therefore, the lowest common multiple of 989,488,910,620,305 is 6807524360.
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.
989 x 488 x 910 x 620 x 305 = 83051797192000
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.
989 : 1, 23, 43, 989
488 : 1, 2, 4, 8, 61, 122, 244, 488
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,488,910,620,305, is 1.
Now, the common factors can be found like this.
989:23x 43
488:2x 2x 2x 61
910:2x 5x 7x 13
620:2x 2x 5x 31
305:5x 61
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 5x 5x 61 = 12200
Therefore, the value for common factors is 12200.
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 = 83051797192000/(1x12200)
LCM = 83051797192000/12200
LCM = 6807524360
Thus, we can understand that the LCM of 989,488,910,620,305 is 6807524360.
