Given numbers are 698,741,459,820,815
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,741,459,820,815 is 5288548877820.
Find LCM of 698,741,459,820,815 with Prime Factorization
| 2 | 698, 741, 459, 820, 815 |
| 3 | 349, 741, 459, 410, 815 |
| 5 | 349, 247, 153, 410, 815 |
| 349, 247, 153, 82, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 349 x 247 x 153 x 82 x 163 = 5288548877820
Therefore, the lowest common multiple of 698,741,459,820,815 is 5288548877820.
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.
698 x 741 x 459 x 820 x 815 = 158656466334600
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.
698 : 1, 2, 349, 698
741 : 1, 3, 13, 19, 39, 57, 247, 741
459 : 1, 3, 9, 17, 27, 51, 153, 459
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,741,459,820,815, is 1.
Now, the common factors can be found like this.
698:2x 349
741:3x 13x 19
459:3x 3x 3x 17
820:2x 2x 5x 41
815:5x 163
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 5 = 30
Therefore, the value for common factors is 30.
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 = 158656466334600/(1x30)
LCM = 158656466334600/30
LCM = 5288548877820
Thus, we can understand that the LCM of 698,741,459,820,815 is 5288548877820.
