Given numbers are 741,385,525,407
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,385,525,407 is 52777725.
Find LCM of 741,385,525,407 with Prime Factorization
| 3 | 741, 385, 525, 407 |
| 5 | 247, 385, 175, 407 |
| 7 | 247, 77, 35, 407 |
| 11 | 247, 11, 5, 407 |
| 247, 1, 5, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 11 x 247 x 1 x 5 x 37 = 52777725
Therefore, the lowest common multiple of 741,385,525,407 is 52777725.
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.
741 x 385 x 525 x 407 = 60958272375
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
385 : 1, 5, 7, 11, 35, 55, 77, 385
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,385,525,407, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
385:5x 7x 11
525:3x 5x 5x 7
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 11 = 1155
Therefore, the value for common factors is 1155.
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 = 60958272375/(1x1155)
LCM = 60958272375/1155
LCM = 52777725
Thus, we can understand that the LCM of 741,385,525,407 is 52777725.
