The LCM of 624,388,286,695 is 462736560.
Find LCM of 624,388,286,695 with Prime Factorization
| 2 | 624, 388, 286, 695 |
| 2 | 312, 194, 143, 695 |
| 13 | 156, 97, 143, 695 |
| 12, 97, 11, 695 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 12 x 97 x 11 x 695 = 462736560
Therefore, the lowest common multiple of 624,388,286,695 is 462736560.
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 388 x 286 x 695 = 48124602240
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
388 : 1, 2, 4, 97, 194, 388
286 : 1, 2, 11, 13, 22, 26, 143, 286
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,388,286,695, is 1.
Now, the common factors can be found like this.
624:2x 2x 2x 2x 3x 13
388:2x 2x 97
286:2x 11x 13
695:5x 139
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 13 = 104
Therefore, the value for common factors is 104.
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 = 48124602240/(1x104)
LCM = 48124602240/104
LCM = 462736560
Thus, we can understand that the LCM of 624,388,286,695 is 462736560.
