Given numbers are 345,566,720,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,566,720,849 is 4686480.
Find LCM of 345,566,720,849 with Prime Factorization
| 2 | 345, 566, 720, 849 |
| 3 | 345, 283, 360, 849 |
| 5 | 115, 283, 120, 283 |
| 283 | 23, 283, 24, 283 |
| 23, 1, 24, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 283 x 23 x 1 x 24 x 1 = 4686480
Therefore, the lowest common multiple of 345,566,720,849 is 4686480.
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.
345 x 566 x 720 x 849 = 119364645600
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
566 : 1, 2, 283, 566
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,566,720,849, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
566:2x 283
720:2x 2x 2x 2x 3x 3x 5
849:3x 283
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 5x 283 = 25470
Therefore, the value for common factors is 25470.
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 = 119364645600/(1x25470)
LCM = 119364645600/25470
LCM = 4686480
Thus, we can understand that the LCM of 345,566,720,849 is 4686480.
