Given numbers are 418,661,645,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,661,645,803 is 13009491330.
Find LCM of 418,661,645,803 with Prime Factorization
| 11 | 418, 661, 645, 803 |
| 38, 661, 645, 73 |
Multiply the prime numbers at the bottom and the left side.
11 x 38 x 661 x 645 x 73 = 13009491330
Therefore, the lowest common multiple of 418,661,645,803 is 13009491330.
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.
418 x 661 x 645 x 803 = 143104404630
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
661 : 1, 661
645 : 1, 3, 5, 15, 43, 129, 215, 645
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,661,645,803, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
661:661
645:3x 5x 43
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 143104404630/(1x11)
LCM = 143104404630/11
LCM = 13009491330
Thus, we can understand that the LCM of 418,661,645,803 is 13009491330.
