Given numbers are 478,242,150,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,242,150,660 is 8675700.
Find LCM of 478,242,150,660 with Prime Factorization
| 2 | 478, 242, 150, 660 |
| 3 | 239, 121, 75, 330 |
| 5 | 239, 121, 25, 110 |
| 11 | 239, 121, 5, 22 |
| 239, 11, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 239 x 11 x 5 x 2 = 8675700
Therefore, the lowest common multiple of 478,242,150,660 is 8675700.
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.
478 x 242 x 150 x 660 = 11451924000
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.
478 : 1, 2, 239, 478
242 : 1, 2, 11, 22, 121, 242
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,242,150,660, is 2.
Now, the common factors can be found like this.
478:2x 239
242:2x 11x 11
150:2x 3x 5x 5
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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 11451924000/(2x660)
LCM = 11451924000/1320
LCM = 8675700
Thus, we can understand that the LCM of 478,242,150,660 is 8675700.
