Given numbers are 913,308,830,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,308,830,840 is 766920.
Find LCM of 913,308,830,840 with Prime Factorization
| 2 | 913, 308, 830, 840 |
| 2 | 913, 154, 415, 420 |
| 5 | 913, 77, 415, 210 |
| 7 | 913, 77, 83, 42 |
| 11 | 913, 11, 83, 6 |
| 83 | 83, 1, 83, 6 |
| 1, 1, 1, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 83 x 1 x 1 x 1 x 6 = 766920
Therefore, the lowest common multiple of 913,308,830,840 is 766920.
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.
913 x 308 x 830 x 840 = 196055428800
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.
913 : 1, 11, 83, 913
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
830 : 1, 2, 5, 10, 83, 166, 415, 830
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,308,830,840, is 1.
Now, the common factors can be found like this.
913:11x 83
308:2x 2x 7x 11
830:2x 5x 83
840:2x 2x 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 2x 2x 5x 7x 11x 83 = 255640
Therefore, the value for common factors is 255640.
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 = 196055428800/(1x255640)
LCM = 196055428800/255640
LCM = 766920
Thus, we can understand that the LCM of 913,308,830,840 is 766920.
