Given numbers are 998,885,767,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,885,767,705 is 539653530.
Find LCM of 998,885,767,705 with Prime Factorization
| 3 | 998, 885, 767, 705 |
| 5 | 998, 295, 767, 235 |
| 59 | 998, 59, 767, 47 |
| 998, 1, 13, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 59 x 998 x 1 x 13 x 47 = 539653530
Therefore, the lowest common multiple of 998,885,767,705 is 539653530.
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.
998 x 885 x 767 x 705 = 477593374050
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.
998 : 1, 2, 499, 998
885 : 1, 3, 5, 15, 59, 177, 295, 885
767 : 1, 13, 59, 767
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,885,767,705, is 1.
Now, the common factors can be found like this.
998:2x 499
885:3x 5x 59
767:13x 59
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 59 = 885
Therefore, the value for common factors is 885.
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 = 477593374050/(1x885)
LCM = 477593374050/885
LCM = 539653530
Thus, we can understand that the LCM of 998,885,767,705 is 539653530.
