Given numbers are 781,916,460,229
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,916,460,229 is 82270540.
Find LCM of 781,916,460,229 with Prime Factorization
| 2 | 781, 916, 460, 229 |
| 2 | 781, 458, 230, 229 |
| 229 | 781, 229, 115, 229 |
| 781, 1, 115, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 229 x 781 x 1 x 115 x 1 = 82270540
Therefore, the lowest common multiple of 781,916,460,229 is 82270540.
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.
781 x 916 x 460 x 229 = 75359814640
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.
781 : 1, 11, 71, 781
916 : 1, 2, 4, 229, 458, 916
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
229 : 1, 229
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,916,460,229, is 1.
Now, the common factors can be found like this.
781:11x 71
916:2x 2x 229
460:2x 2x 5x 23
229:229
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 229 = 916
Therefore, the value for common factors is 916.
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 = 75359814640/(1x916)
LCM = 75359814640/916
LCM = 82270540
Thus, we can understand that the LCM of 781,916,460,229 is 82270540.
