Given numbers are 513,451,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,451,894 is 68946174.
Find LCM of 513,451,894 with Prime Factorization
| 3 | 513, 451, 894 |
| 171, 451, 298 |
Multiply the prime numbers at the bottom and the left side.
3 x 171 x 451 x 298 = 68946174
Therefore, the lowest common multiple of 513,451,894 is 68946174.
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.
513 x 451 x 894 = 206838522
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
451 : 1, 11, 41, 451
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,451,894, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
451:11x 41
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 206838522/(1x3)
LCM = 206838522/3
LCM = 68946174
Thus, we can understand that the LCM of 513,451,894 is 68946174.
