Given numbers are 864,812,919,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 864,812,919,899 is 4996742688.
Find LCM of 864,812,919,899 with Prime Factorization
| 2 | 864, 812, 919, 899 |
| 2 | 432, 406, 919, 899 |
| 29 | 216, 203, 919, 899 |
| 216, 7, 919, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 216 x 7 x 919 x 31 = 4996742688
Therefore, the lowest common multiple of 864,812,919,899 is 4996742688.
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.
864 x 812 x 919 x 899 = 579622151808
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.
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
919 : 1, 919
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 864,812,919,899, is 1.
Now, the common factors can be found like this.
864:2x 2x 2x 2x 2x 3x 3x 3
812:2x 2x 7x 29
919:919
899:29x 31
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 29 = 116
Therefore, the value for common factors is 116.
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 = 579622151808/(1x116)
LCM = 579622151808/116
LCM = 4996742688
Thus, we can understand that the LCM of 864,812,919,899 is 4996742688.
