Given numbers are 492,645,849,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,645,849,878 is 13141789860.
Find LCM of 492,645,849,878 with Prime Factorization
| 2 | 492, 645, 849, 878 |
| 3 | 246, 645, 849, 439 |
| 82, 215, 283, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 82 x 215 x 283 x 439 = 13141789860
Therefore, the lowest common multiple of 492,645,849,878 is 13141789860.
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.
492 x 645 x 849 x 878 = 236552217480
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
645 : 1, 3, 5, 15, 43, 129, 215, 645
849 : 1, 3, 283, 849
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,645,849,878, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
645:3x 5x 43
849:3x 283
878:2x 439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 236552217480/(1x18)
LCM = 236552217480/18
LCM = 13141789860
Thus, we can understand that the LCM of 492,645,849,878 is 13141789860.
