Given numbers are 741,418,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,418,715 is 81510.
Find LCM of 741,418,715 with Prime Factorization
| 11 | 741, 418, 715 |
| 13 | 741, 38, 65 |
| 19 | 57, 38, 5 |
| 3, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 19 x 3 x 2 x 5 = 81510
Therefore, the lowest common multiple of 741,418,715 is 81510.
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 418 x 715 = 221462670
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,418,715, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
418:2x 11x 19
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13x 19 = 2717
Therefore, the value for common factors is 2717.
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 = 221462670/(1x2717)
LCM = 221462670/2717
LCM = 81510
Thus, we can understand that the LCM of 741,418,715 is 81510.
