Given numbers are 435,261,741,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 435,261,741,665 is 2256345.
Find LCM of 435,261,741,665 with Prime Factorization
| 3 | 435, 261, 741, 665 |
| 5 | 145, 87, 247, 665 |
| 19 | 29, 87, 247, 133 |
| 29 | 29, 87, 13, 7 |
| 1, 3, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 29 x 1 x 3 x 13 x 7 = 2256345
Therefore, the lowest common multiple of 435,261,741,665 is 2256345.
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.
435 x 261 x 741 x 665 = 55946074275
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.
435 : 1, 3, 5, 15, 29, 87, 145, 435
261 : 1, 3, 9, 29, 87, 261
741 : 1, 3, 13, 19, 39, 57, 247, 741
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 435,261,741,665, is 1.
Now, the common factors can be found like this.
435:3x 5x 29
261:3x 3x 29
741:3x 13x 19
665:5x 7x 19
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 5x 19x 29 = 24795
Therefore, the value for common factors is 24795.
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 = 55946074275/(1x24795)
LCM = 55946074275/24795
LCM = 2256345
Thus, we can understand that the LCM of 435,261,741,665 is 2256345.
