Given numbers are 449,791,124,894,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 449,791,124,894,642 is 2106375576564.
Find LCM of 449,791,124,894,642 with Prime Factorization
| 2 | 449, 791, 124, 894, 642 |
| 3 | 449, 791, 62, 447, 321 |
| 449, 791, 62, 149, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 449 x 791 x 62 x 149 x 107 = 2106375576564
Therefore, the lowest common multiple of 449,791,124,894,642 is 2106375576564.
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.
449 x 791 x 124 x 894 x 642 = 25276506918768
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.
449 : 1, 449
791 : 1, 7, 113, 791
124 : 1, 2, 4, 31, 62, 124
894 : 1, 2, 3, 6, 149, 298, 447, 894
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,791,124,894,642, is 1.
Now, the common factors can be found like this.
449:449
791:7x 113
124:2x 2x 31
894:2x 3x 149
642:2x 3x 107
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 3 = 12
Therefore, the value for common factors is 12.
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 = 25276506918768/(1x12)
LCM = 25276506918768/12
LCM = 2106375576564
Thus, we can understand that the LCM of 449,791,124,894,642 is 2106375576564.
