Given numbers are 478,920,670,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,920,670,955 is 2813804360.
Find LCM of 478,920,670,955 with Prime Factorization
| 2 | 478, 920, 670, 955 |
| 5 | 239, 460, 335, 955 |
| 239, 92, 67, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 239 x 92 x 67 x 191 = 2813804360
Therefore, the lowest common multiple of 478,920,670,955 is 2813804360.
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 920 x 670 x 955 = 281380436000
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
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
670 : 1, 2, 5, 10, 67, 134, 335, 670
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,920,670,955, is 1.
Now, the common factors can be found like this.
478:2x 239
920:2x 2x 2x 5x 23
670:2x 5x 67
955:5x 191
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 281380436000/(1x100)
LCM = 281380436000/100
LCM = 2813804360
Thus, we can understand that the LCM of 478,920,670,955 is 2813804360.
