Given numbers are 447,985,354,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,985,354,812 is 21093652860.
Find LCM of 447,985,354,812 with Prime Factorization
| 2 | 447, 985, 354, 812 |
| 3 | 447, 985, 177, 406 |
| 149, 985, 59, 406 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 985 x 59 x 406 = 21093652860
Therefore, the lowest common multiple of 447,985,354,812 is 21093652860.
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.
447 x 985 x 354 x 812 = 126561917160
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.
447 : 1, 3, 149, 447
985 : 1, 5, 197, 985
354 : 1, 2, 3, 6, 59, 118, 177, 354
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,985,354,812, is 1.
Now, the common factors can be found like this.
447:3x 149
985:5x 197
354:2x 3x 59
812:2x 2x 7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 126561917160/(1x6)
LCM = 126561917160/6
LCM = 21093652860
Thus, we can understand that the LCM of 447,985,354,812 is 21093652860.
