Given numbers are 687,916,577,675
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,916,577,675 is 356759100.
Find LCM of 687,916,577,675 with Prime Factorization
| 3 | 687, 916, 577, 675 |
| 229 | 229, 916, 577, 225 |
| 1, 4, 577, 225 |
Multiply the prime numbers at the bottom and the left side.
3 x 229 x 1 x 4 x 577 x 225 = 356759100
Therefore, the lowest common multiple of 687,916,577,675 is 356759100.
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.
687 x 916 x 577 x 675 = 245093501700
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.
687 : 1, 3, 229, 687
916 : 1, 2, 4, 229, 458, 916
577 : 1, 577
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,916,577,675, is 1.
Now, the common factors can be found like this.
687:3x 229
916:2x 2x 229
577:577
675:3x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 229 = 687
Therefore, the value for common factors is 687.
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 = 245093501700/(1x687)
LCM = 245093501700/687
LCM = 356759100
Thus, we can understand that the LCM of 687,916,577,675 is 356759100.
