Given numbers are 741,609,665,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,609,665,489 is 122594745.
Find LCM of 741,609,665,489 with Prime Factorization
| 3 | 741, 609, 665, 489 |
| 7 | 247, 203, 665, 163 |
| 19 | 247, 29, 95, 163 |
| 13, 29, 5, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 13 x 29 x 5 x 163 = 122594745
Therefore, the lowest common multiple of 741,609,665,489 is 122594745.
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.
741 x 609 x 665 x 489 = 146745909765
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
609 : 1, 3, 7, 21, 29, 87, 203, 609
665 : 1, 5, 7, 19, 35, 95, 133, 665
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,609,665,489, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
609:3x 7x 29
665:5x 7x 19
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 19 = 1197
Therefore, the value for common factors is 1197.
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 = 146745909765/(1x1197)
LCM = 146745909765/1197
LCM = 122594745
Thus, we can understand that the LCM of 741,609,665,489 is 122594745.
