Find LCM of 664,826,869,812,385 with Prime Factorization
| 2 | 664, 826, 869, 812, 385 |
| 2 | 332, 413, 869, 406, 385 |
| 7 | 166, 413, 869, 203, 385 |
| 11 | 166, 59, 869, 29, 55 |
| 166, 59, 79, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 166 x 59 x 79 x 29 x 5 = 34554603160
Therefore, the lowest common multiple of 664,826,869,812,385 is 34554603160.
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.
664 x 826 x 869 x 812 x 385 = 148999448825920
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
826 : 1, 2, 7, 14, 59, 118, 413, 826
869 : 1, 11, 79, 869
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,826,869,812,385, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
826:2x 7x 59
869:11x 79
812:2x 2x 7x 29
385:5x 7x 11
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 7x 7x 11 = 4312
Therefore, the value for common factors is 4312.
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 = 148999448825920/(1x4312)
LCM = 148999448825920/4312
LCM = 34554603160
Thus, we can understand that the LCM of 664,826,869,812,385 is 34554603160.
