Given numbers are 100,401,667,326,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,401,667,326,660 is 143870499300.
Find LCM of 100,401,667,326,660 with Prime Factorization
| 2 | 100, 401, 667, 326, 660 |
| 2 | 50, 401, 667, 163, 330 |
| 5 | 25, 401, 667, 163, 165 |
| 5, 401, 667, 163, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 401 x 667 x 163 x 33 = 143870499300
Therefore, the lowest common multiple of 100,401,667,326,660 is 143870499300.
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.
100 x 401 x 667 x 326 x 660 = 5754819972000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
401 : 1, 401
667 : 1, 23, 29, 667
326 : 1, 2, 163, 326
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,401,667,326,660, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
401:401
667:23x 29
326:2x 163
660:2x 2x 3x 5x 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 5 = 40
Therefore, the value for common factors is 40.
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 = 5754819972000/(1x40)
LCM = 5754819972000/40
LCM = 143870499300
Thus, we can understand that the LCM of 100,401,667,326,660 is 143870499300.
