Given numbers are 414,917,987,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 414,917,987,909 is 1802141586.
Find LCM of 414,917,987,909 with Prime Factorization
| 3 | 414, 917, 987, 909 |
| 3 | 138, 917, 329, 303 |
| 7 | 46, 917, 329, 101 |
| 46, 131, 47, 101 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 46 x 131 x 47 x 101 = 1802141586
Therefore, the lowest common multiple of 414,917,987,909 is 1802141586.
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.
414 x 917 x 987 x 909 = 340604759754
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.
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
917 : 1, 7, 131, 917
987 : 1, 3, 7, 21, 47, 141, 329, 987
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,917,987,909, is 1.
Now, the common factors can be found like this.
414:2x 3x 3x 23
917:7x 131
987:3x 7x 47
909:3x 3x 101
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 7 = 189
Therefore, the value for common factors is 189.
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 = 340604759754/(1x189)
LCM = 340604759754/189
LCM = 1802141586
Thus, we can understand that the LCM of 414,917,987,909 is 1802141586.
