Given numbers are 667,605,341,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,605,341,155 is 12509585.
Find LCM of 667,605,341,155 with Prime Factorization
| 5 | 667, 605, 341, 155 |
| 11 | 667, 121, 341, 31 |
| 31 | 667, 11, 31, 31 |
| 667, 11, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 31 x 667 x 11 x 1 x 1 = 12509585
Therefore, the lowest common multiple of 667,605,341,155 is 12509585.
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.
667 x 605 x 341 x 155 = 21328842425
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.
667 : 1, 23, 29, 667
605 : 1, 5, 11, 55, 121, 605
341 : 1, 11, 31, 341
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,605,341,155, is 1.
Now, the common factors can be found like this.
667:23x 29
605:5x 11x 11
341:11x 31
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 31 = 1705
Therefore, the value for common factors is 1705.
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 = 21328842425/(1x1705)
LCM = 21328842425/1705
LCM = 12509585
Thus, we can understand that the LCM of 667,605,341,155 is 12509585.
