Given numbers are 991,964,585,463,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,964,585,463,210 is 1811279974140.
Find LCM of 991,964,585,463,210 with Prime Factorization
| 2 | 991, 964, 585, 463, 210 |
| 3 | 991, 482, 585, 463, 105 |
| 5 | 991, 482, 195, 463, 35 |
| 991, 482, 39, 463, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 991 x 482 x 39 x 463 x 7 = 1811279974140
Therefore, the lowest common multiple of 991,964,585,463,210 is 1811279974140.
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.
991 x 964 x 585 x 463 x 210 = 54338399224200
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.
991 : 1, 991
964 : 1, 2, 4, 241, 482, 964
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
463 : 1, 463
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,964,585,463,210, is 1.
Now, the common factors can be found like this.
991:991
964:2x 2x 241
585:3x 3x 5x 13
463:463
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 54338399224200/(1x30)
LCM = 54338399224200/30
LCM = 1811279974140
Thus, we can understand that the LCM of 991,964,585,463,210 is 1811279974140.
