Find LCM of 285,789,714,748,705 with Prime Factorization
| 2 | 285, 789, 714, 748, 705 |
| 3 | 285, 789, 357, 374, 705 |
| 5 | 95, 263, 119, 374, 235 |
| 17 | 19, 263, 119, 374, 47 |
| 19, 263, 7, 22, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 19 x 263 x 7 x 22 x 47 = 18445825860
Therefore, the lowest common multiple of 285,789,714,748,705 is 18445825860.
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 789 x 714 x 748 x 705 = 84666340697400
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
789 : 1, 3, 263, 789
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
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 285,789,714,748,705, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
789:3x 263
714:2x 3x 7x 17
748:2x 2x 11x 17
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 3x 3x 3x 5x 17 = 4590
Therefore, the value for common factors is 4590.
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 = 84666340697400/(1x4590)
LCM = 84666340697400/4590
LCM = 18445825860
Thus, we can understand that the LCM of 285,789,714,748,705 is 18445825860.
