Given numbers are 804,407,665,197,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,407,665,197,666 is 128605512420.
Find LCM of 804,407,665,197,666 with Prime Factorization
| 2 | 804, 407, 665, 197, 666 |
| 3 | 402, 407, 665, 197, 333 |
| 37 | 134, 407, 665, 197, 111 |
| 134, 11, 665, 197, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 134 x 11 x 665 x 197 x 3 = 128605512420
Therefore, the lowest common multiple of 804,407,665,197,666 is 128605512420.
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.
804 x 407 x 665 x 197 x 666 = 28550423757240
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
407 : 1, 11, 37, 407
665 : 1, 5, 7, 19, 35, 95, 133, 665
197 : 1, 197
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,407,665,197,666, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
407:11x 37
665:5x 7x 19
197:197
666:2x 3x 3x 37
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 37 = 222
Therefore, the value for common factors is 222.
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 = 28550423757240/(1x222)
LCM = 28550423757240/222
LCM = 128605512420
Thus, we can understand that the LCM of 804,407,665,197,666 is 128605512420.
