Given numbers are 3,285,741,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 3,285,741,649 is 2404545.
Find LCM of 3,285,741,649 with Prime Factorization
3 | 3, 285, 741, 649 |
19 | 1, 95, 247, 649 |
1, 5, 13, 649 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 1 x 5 x 13 x 649 = 2404545
Therefore, the lowest common multiple of 3,285,741,649 is 2404545.
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.
3 x 285 x 741 x 649 = 411177195
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.
3 : 1, 3
285 : 1, 3, 5, 15, 19, 57, 95, 285
741 : 1, 3, 13, 19, 39, 57, 247, 741
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,285,741,649, is 1.
Now, the common factors can be found like this.
3:3
285:3x 5x 19
741:3x 13x 19
649:11x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
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 = 411177195/(1x171)
LCM = 411177195/171
LCM = 2404545
Thus, we can understand that the LCM of 3,285,741,649 is 2404545.
