Given numbers are 662,312,232,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 662,312,232,689 is 158729064.
Find LCM of 662,312,232,689 with Prime Factorization
| 2 | 662, 312, 232, 689 |
| 2 | 331, 156, 116, 689 |
| 2 | 331, 78, 58, 689 |
| 13 | 331, 39, 29, 689 |
| 331, 3, 29, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 331 x 3 x 29 x 53 = 158729064
Therefore, the lowest common multiple of 662,312,232,689 is 158729064.
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 312 x 232 x 689 = 33015645312
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
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
232 : 1, 2, 4, 8, 29, 58, 116, 232
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 662,312,232,689, is 1.
Now, the common factors can be found like this.
662:2x 331
312:2x 2x 2x 3x 13
232:2x 2x 2x 29
689:13x 53
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 13 = 208
Therefore, the value for common factors is 208.
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 = 33015645312/(1x208)
LCM = 33015645312/208
LCM = 158729064
Thus, we can understand that the LCM of 662,312,232,689 is 158729064.
