Find LCM of 855,420,925,405,513 with Prime Factorization
| 3 | 855, 420, 925, 405, 513 |
| 3 | 285, 140, 925, 135, 171 |
| 3 | 95, 140, 925, 45, 57 |
| 5 | 95, 140, 925, 15, 19 |
| 19 | 19, 28, 185, 3, 19 |
| 1, 28, 185, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 19 x 1 x 28 x 185 x 3 x 1 = 39860100
Therefore, the lowest common multiple of 855,420,925,405,513 is 39860100.
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 420 x 925 x 405 x 513 = 69012780637500
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
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
925 : 1, 5, 25, 37, 185, 925
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
513 : 1, 3, 9, 19, 27, 57, 171, 513
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,420,925,405,513, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
420:2x 2x 3x 5x 7
925:5x 5x 37
405:3x 3x 3x 3x 5
513:3x 3x 3x 19
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 3x 3x 3x 5x 5x 5x 19 = 1731375
Therefore, the value for common factors is 1731375.
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 = 69012780637500/(1x1731375)
LCM = 69012780637500/1731375
LCM = 39860100
Thus, we can understand that the LCM of 855,420,925,405,513 is 39860100.
