Given numbers are 491,968,660,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,968,660,872 is 777095880.
Find LCM of 491,968,660,872 with Prime Factorization
| 2 | 491, 968, 660, 872 |
| 2 | 491, 484, 330, 436 |
| 2 | 491, 242, 165, 218 |
| 11 | 491, 121, 165, 109 |
| 491, 11, 15, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 491 x 11 x 15 x 109 = 777095880
Therefore, the lowest common multiple of 491,968,660,872 is 777095880.
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.
491 x 968 x 660 x 872 = 273537749760
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.
491 : 1, 491
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
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
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,968,660,872, is 1.
Now, the common factors can be found like this.
491:491
968:2x 2x 2x 11x 11
660:2x 2x 3x 5x 11
872:2x 2x 2x 109
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 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 273537749760/(1x352)
LCM = 273537749760/352
LCM = 777095880
Thus, we can understand that the LCM of 491,968,660,872 is 777095880.
