Given numbers are 445,909,447,675,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 445,909,447,675,669 is 201607314525.
Find LCM of 445,909,447,675,669 with Prime Factorization
| 3 | 445, 909, 447, 675, 669 |
| 3 | 445, 303, 149, 225, 223 |
| 5 | 445, 101, 149, 75, 223 |
| 89, 101, 149, 15, 223 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 89 x 101 x 149 x 15 x 223 = 201607314525
Therefore, the lowest common multiple of 445,909,447,675,669 is 201607314525.
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.
445 x 909 x 447 x 675 x 669 = 81650962382625
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.
445 : 1, 5, 89, 445
909 : 1, 3, 9, 101, 303, 909
447 : 1, 3, 149, 447
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,909,447,675,669, is 1.
Now, the common factors can be found like this.
445:5x 89
909:3x 3x 101
447:3x 149
675:3x 3x 3x 5x 5
669:3x 223
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 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 81650962382625/(1x405)
LCM = 81650962382625/405
LCM = 201607314525
Thus, we can understand that the LCM of 445,909,447,675,669 is 201607314525.
