Find LCM of 846,806,988,705 with Prime Factorization
| 2 | 846, 806, 988, 705 |
| 3 | 423, 403, 494, 705 |
| 13 | 141, 403, 494, 235 |
| 47 | 141, 31, 38, 235 |
| 3, 31, 38, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 47 x 3 x 31 x 38 x 5 = 64778220
Therefore, the lowest common multiple of 846,806,988,705 is 64778220.
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.
846 x 806 x 988 x 705 = 474953909040
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.
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
806 : 1, 2, 13, 26, 31, 62, 403, 806
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
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 846,806,988,705, is 1.
Now, the common factors can be found like this.
846:2x 3x 3x 47
806:2x 13x 31
988:2x 2x 13x 19
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.
2x 2x 3x 13x 47 = 7332
Therefore, the value for common factors is 7332.
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 = 474953909040/(1x7332)
LCM = 474953909040/7332
LCM = 64778220
Thus, we can understand that the LCM of 846,806,988,705 is 64778220.
