Given numbers are 353,988,120,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 353,988,120,816 is 355739280.
Find LCM of 353,988,120,816 with Prime Factorization
| 2 | 353, 988, 120, 816 |
| 2 | 353, 494, 60, 408 |
| 2 | 353, 247, 30, 204 |
| 3 | 353, 247, 15, 102 |
| 353, 247, 5, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 353 x 247 x 5 x 34 = 355739280
Therefore, the lowest common multiple of 353,988,120,816 is 355739280.
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 988 x 120 x 816 = 34150970880
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
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,988,120,816, is 1.
Now, the common factors can be found like this.
353:353
988:2x 2x 13x 19
120:2x 2x 2x 3x 5
816:2x 2x 2x 2x 3x 17
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 2x 3 = 96
Therefore, the value for common factors is 96.
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 = 34150970880/(1x96)
LCM = 34150970880/96
LCM = 355739280
Thus, we can understand that the LCM of 353,988,120,816 is 355739280.
