Find LCM of 791,115,285,153,612 with Prime Factorization
| 3 | 791, 115, 285, 153, 612 |
| 3 | 791, 115, 95, 51, 204 |
| 5 | 791, 115, 95, 17, 68 |
| 17 | 791, 23, 19, 17, 68 |
| 791, 23, 19, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 791 x 23 x 19 x 1 x 4 = 1057741020
Therefore, the lowest common multiple of 791,115,285,153,612 is 1057741020.
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.
791 x 115 x 285 x 153 x 612 = 2427515640900
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.
791 : 1, 7, 113, 791
115 : 1, 5, 23, 115
285 : 1, 3, 5, 15, 19, 57, 95, 285
153 : 1, 3, 9, 17, 51, 153
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,115,285,153,612, is 1.
Now, the common factors can be found like this.
791:7x 113
115:5x 23
285:3x 5x 19
153:3x 3x 17
612:2x 2x 3x 3x 17
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 3x 5x 17 = 2295
Therefore, the value for common factors is 2295.
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 = 2427515640900/(1x2295)
LCM = 2427515640900/2295
LCM = 1057741020
Thus, we can understand that the LCM of 791,115,285,153,612 is 1057741020.
