Given numbers are 408,764,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,764,849 is 22053624.
Find LCM of 408,764,849 with Prime Factorization
| 2 | 408, 764, 849 |
| 2 | 204, 382, 849 |
| 3 | 102, 191, 849 |
| 34, 191, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 34 x 191 x 283 = 22053624
Therefore, the lowest common multiple of 408,764,849 is 22053624.
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.
408 x 764 x 849 = 264643488
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
764 : 1, 2, 4, 191, 382, 764
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,764,849, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
764:2x 2x 191
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 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 264643488/(1x12)
LCM = 264643488/12
LCM = 22053624
Thus, we can understand that the LCM of 408,764,849 is 22053624.
