Given numbers are 285,622,946,963,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,622,946,963,989 is 619055025930.
Find LCM of 285,622,946,963,989 with Prime Factorization
| 2 | 285, 622, 946, 963, 989 |
| 3 | 285, 311, 473, 963, 989 |
| 43 | 95, 311, 473, 321, 989 |
| 95, 311, 11, 321, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 95 x 311 x 11 x 321 x 23 = 619055025930
Therefore, the lowest common multiple of 285,622,946,963,989 is 619055025930.
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.
285 x 622 x 946 x 963 x 989 = 159716196689940
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
622 : 1, 2, 311, 622
946 : 1, 2, 11, 22, 43, 86, 473, 946
963 : 1, 3, 9, 107, 321, 963
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,622,946,963,989, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
622:2x 311
946:2x 11x 43
963:3x 3x 107
989:23x 43
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 43 = 258
Therefore, the value for common factors is 258.
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 = 159716196689940/(1x258)
LCM = 159716196689940/258
LCM = 619055025930
Thus, we can understand that the LCM of 285,622,946,963,989 is 619055025930.
