Given numbers are 209,159,921,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,159,921,440 is 408076680.
Find LCM of 209,159,921,440 with Prime Factorization
| 3 | 209, 159, 921, 440 |
| 11 | 209, 53, 307, 440 |
| 19, 53, 307, 40 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 19 x 53 x 307 x 40 = 408076680
Therefore, the lowest common multiple of 209,159,921,440 is 408076680.
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.
209 x 159 x 921 x 440 = 13466530440
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.
209 : 1, 11, 19, 209
159 : 1, 3, 53, 159
921 : 1, 3, 307, 921
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,159,921,440, is 1.
Now, the common factors can be found like this.
209:11x 19
159:3x 53
921:3x 307
440:2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 13466530440/(1x33)
LCM = 13466530440/33
LCM = 408076680
Thus, we can understand that the LCM of 209,159,921,440 is 408076680.
