Find LCM of 855,722,285,509,956 with Prime Factorization
| 2 | 855, 722, 285, 509, 956 |
| 3 | 855, 361, 285, 509, 478 |
| 5 | 95, 361, 285, 509, 478 |
| 19 | 19, 361, 57, 509, 478 |
| 1, 19, 3, 509, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 19 x 3 x 509 x 478 = 7904881980
Therefore, the lowest common multiple of 855,722,285,509,956 is 7904881980.
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.
855 x 722 x 285 x 509 x 956 = 85609871843400
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
722 : 1, 2, 19, 38, 361, 722
285 : 1, 3, 5, 15, 19, 57, 95, 285
509 : 1, 509
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,722,285,509,956, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
722:2x 19x 19
285:3x 5x 19
509:509
956:2x 2x 239
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 5x 19x 19 = 10830
Therefore, the value for common factors is 10830.
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 = 85609871843400/(1x10830)
LCM = 85609871843400/10830
LCM = 7904881980
Thus, we can understand that the LCM of 855,722,285,509,956 is 7904881980.
