Given numbers are 812,116,916,768,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,116,916,768,491 is 17529689856.
Find LCM of 812,116,916,768,491 with Prime Factorization
| 2 | 812, 116, 916, 768, 491 |
| 2 | 406, 58, 458, 384, 491 |
| 29 | 203, 29, 229, 192, 491 |
| 7, 1, 229, 192, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 7 x 1 x 229 x 192 x 491 = 17529689856
Therefore, the lowest common multiple of 812,116,916,768,491 is 17529689856.
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.
812 x 116 x 916 x 768 x 491 = 32535104372736
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
116 : 1, 2, 4, 29, 58, 116
916 : 1, 2, 4, 229, 458, 916
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,116,916,768,491, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
116:2x 2x 29
916:2x 2x 229
768:2x 2x 2x 2x 2x 2x 2x 2x 3
491:491
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 2x 29 = 1856
Therefore, the value for common factors is 1856.
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 = 32535104372736/(1x1856)
LCM = 32535104372736/1856
LCM = 17529689856
Thus, we can understand that the LCM of 812,116,916,768,491 is 17529689856.
