The LCM of 624,360,855,324 is 1600560.
Find LCM of 624,360,855,324 with Prime Factorization
| 2 | 624, 360, 855, 324 |
| 2 | 312, 180, 855, 162 |
| 2 | 156, 90, 855, 81 |
| 3 | 78, 45, 855, 81 |
| 3 | 26, 15, 285, 27 |
| 5 | 26, 5, 95, 9 |
| 26, 1, 19, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 26 x 1 x 19 x 9 = 1600560
Therefore, the lowest common multiple of 624,360,855,324 is 1600560.
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.
624 x 360 x 855 x 324 = 62229772800
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.
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,360,855,324, is 3.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
360:2x 2x 2x 3x 3x 5
855:3x 3x 5x 19
324:2x 2x 3x 3x 3x 3
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 2x 3x 3x 3x 3x 5 = 12960
Therefore, the value for common factors is 12960.
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 = 62229772800/(3x12960)
LCM = 62229772800/38880
LCM = 1600560
Thus, we can understand that the LCM of 624,360,855,324 is 1600560.
