Given numbers are 398,268,722,532,209
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,268,722,532,209 is 1482469604.
Find LCM of 398,268,722,532,209 with Prime Factorization
| 2 | 398, 268, 722, 532, 209 |
| 2 | 199, 134, 361, 266, 209 |
| 19 | 199, 67, 361, 133, 209 |
| 199, 67, 19, 7, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 199 x 67 x 19 x 7 x 11 = 1482469604
Therefore, the lowest common multiple of 398,268,722,532,209 is 1482469604.
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.
398 x 268 x 722 x 532 x 209 = 8562744432704
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.
398 : 1, 2, 199, 398
268 : 1, 2, 4, 67, 134, 268
722 : 1, 2, 19, 38, 361, 722
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
209 : 1, 11, 19, 209
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,268,722,532,209, is 1.
Now, the common factors can be found like this.
398:2x 199
268:2x 2x 67
722:2x 19x 19
532:2x 2x 7x 19
209:11x 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 2x 2x 2x 19x 19 = 5776
Therefore, the value for common factors is 5776.
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 = 8562744432704/(1x5776)
LCM = 8562744432704/5776
LCM = 1482469604
Thus, we can understand that the LCM of 398,268,722,532,209 is 1482469604.
