Given numbers are 905,906,278,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,906,278,139 is 113970270.
Find LCM of 905,906,278,139 with Prime Factorization
| 2 | 905, 906, 278, 139 |
| 139 | 905, 453, 139, 139 |
| 905, 453, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 905 x 453 x 1 x 1 = 113970270
Therefore, the lowest common multiple of 905,906,278,139 is 113970270.
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 906 x 278 x 139 = 31683735060
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
906 : 1, 2, 3, 6, 151, 302, 453, 906
278 : 1, 2, 139, 278
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,906,278,139, is 1.
Now, the common factors can be found like this.
905:5x 181
906:2x 3x 151
278:2x 139
139:139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 139 = 278
Therefore, the value for common factors is 278.
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 = 31683735060/(1x278)
LCM = 31683735060/278
LCM = 113970270
Thus, we can understand that the LCM of 905,906,278,139 is 113970270.
