Given numbers are 830,345,256,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,345,256,310 is 227247360.
Find LCM of 830,345,256,310 with Prime Factorization
| 2 | 830, 345, 256, 310 |
| 5 | 415, 345, 128, 155 |
| 83, 69, 128, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 83 x 69 x 128 x 31 = 227247360
Therefore, the lowest common multiple of 830,345,256,310 is 227247360.
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.
830 x 345 x 256 x 310 = 22724736000
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
345 : 1, 3, 5, 15, 23, 69, 115, 345
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,345,256,310, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
345:3x 5x 23
256:2x 2x 2x 2x 2x 2x 2x 2
310:2x 5x 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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 22724736000/(1x100)
LCM = 22724736000/100
LCM = 227247360
Thus, we can understand that the LCM of 830,345,256,310 is 227247360.
