Given numbers are 662,728,612,609
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,728,612,609 is 1069175016.
Find LCM of 662,728,612,609 with Prime Factorization
| 2 | 662, 728, 612, 609 |
| 2 | 331, 364, 306, 609 |
| 3 | 331, 182, 153, 609 |
| 7 | 331, 182, 51, 203 |
| 331, 26, 51, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 331 x 26 x 51 x 29 = 1069175016
Therefore, the lowest common multiple of 662,728,612,609 is 1069175016.
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.
662 x 728 x 612 x 609 = 179621402688
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.
662 : 1, 2, 331, 662
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,728,612,609, is 1.
Now, the common factors can be found like this.
662:2x 331
728:2x 2x 2x 7x 13
612:2x 2x 3x 3x 17
609:3x 7x 29
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 179621402688/(1x168)
LCM = 179621402688/168
LCM = 1069175016
Thus, we can understand that the LCM of 662,728,612,609 is 1069175016.
