Given numbers are 219,921,438,405,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,921,438,405,836 is 7587916380.
Find LCM of 219,921,438,405,836 with Prime Factorization
| 2 | 219, 921, 438, 405, 836 |
| 3 | 219, 921, 219, 405, 418 |
| 73 | 73, 307, 73, 135, 418 |
| 1, 307, 1, 135, 418 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 1 x 307 x 1 x 135 x 418 = 7587916380
Therefore, the lowest common multiple of 219,921,438,405,836 is 7587916380.
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.
219 x 921 x 438 x 405 x 836 = 29911566369960
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.
219 : 1, 3, 73, 219
921 : 1, 3, 307, 921
438 : 1, 2, 3, 6, 73, 146, 219, 438
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,921,438,405,836, is 1.
Now, the common factors can be found like this.
219:3x 73
921:3x 307
438:2x 3x 73
405:3x 3x 3x 3x 5
836:2x 2x 11x 19
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 3x 3x 73 = 3942
Therefore, the value for common factors is 3942.
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 = 29911566369960/(1x3942)
LCM = 29911566369960/3942
LCM = 7587916380
Thus, we can understand that the LCM of 219,921,438,405,836 is 7587916380.
