Given numbers are 905,878,298,115
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,878,298,115 is 2723059930.
Find LCM of 905,878,298,115 with Prime Factorization
| 2 | 905, 878, 298, 115 |
| 5 | 905, 439, 149, 115 |
| 181, 439, 149, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 181 x 439 x 149 x 23 = 2723059930
Therefore, the lowest common multiple of 905,878,298,115 is 2723059930.
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.
905 x 878 x 298 x 115 = 27230599300
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.
905 : 1, 5, 181, 905
878 : 1, 2, 439, 878
298 : 1, 2, 149, 298
115 : 1, 5, 23, 115
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,878,298,115, is 1.
Now, the common factors can be found like this.
905:5x 181
878:2x 439
298:2x 149
115:5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 27230599300/(1x10)
LCM = 27230599300/10
LCM = 2723059930
Thus, we can understand that the LCM of 905,878,298,115 is 2723059930.
