Given numbers are 353,990,487,978,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 353,990,487,978,969 is 8960432816610.
Find LCM of 353,990,487,978,969 with Prime Factorization
| 2 | 353, 990, 487, 978, 969 |
| 3 | 353, 495, 487, 489, 969 |
| 353, 165, 487, 163, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 353 x 165 x 487 x 163 x 323 = 8960432816610
Therefore, the lowest common multiple of 353,990,487,978,969 is 8960432816610.
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.
353 x 990 x 487 x 978 x 969 = 161287790698980
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.
353 : 1, 353
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
487 : 1, 487
978 : 1, 2, 3, 6, 163, 326, 489, 978
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,990,487,978,969, is 1.
Now, the common factors can be found like this.
353:353
990:2x 3x 3x 5x 11
487:487
978:2x 3x 163
969:3x 17x 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 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 = 161287790698980/(1x18)
LCM = 161287790698980/18
LCM = 8960432816610
Thus, we can understand that the LCM of 353,990,487,978,969 is 8960432816610.
