Find LCM of 502,455,728,913,840 with Prime Factorization
| 2 | 502, 455, 728, 913, 840 |
| 2 | 251, 455, 364, 913, 420 |
| 2 | 251, 455, 182, 913, 210 |
| 5 | 251, 455, 91, 913, 105 |
| 7 | 251, 91, 91, 913, 21 |
| 13 | 251, 13, 13, 913, 3 |
| 251, 1, 1, 913, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 13 x 251 x 1 x 1 x 913 x 3 = 2502459960
Therefore, the lowest common multiple of 502,455,728,913,840 is 2502459960.
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.
502 x 455 x 728 x 913 x 840 = 127525359561600
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.
502 : 1, 2, 251, 502
455 : 1, 5, 7, 13, 35, 65, 91, 455
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
913 : 1, 11, 83, 913
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,455,728,913,840, is 1.
Now, the common factors can be found like this.
502:2x 251
455:5x 7x 13
728:2x 2x 2x 7x 13
913:11x 83
840:2x 2x 2x 3x 5x 7
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 2x 2x 5x 7x 7x 13 = 50960
Therefore, the value for common factors is 50960.
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 = 127525359561600/(1x50960)
LCM = 127525359561600/50960
LCM = 2502459960
Thus, we can understand that the LCM of 502,455,728,913,840 is 2502459960.
