Given numbers are 605,719,473,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,719,473,891 is 1515087585.
Find LCM of 605,719,473,891 with Prime Factorization
| 11 | 605, 719, 473, 891 |
| 55, 719, 43, 81 |
Multiply the prime numbers at the bottom and the left side.
11 x 55 x 719 x 43 x 81 = 1515087585
Therefore, the lowest common multiple of 605,719,473,891 is 1515087585.
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.
605 x 719 x 473 x 891 = 183325597785
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.
605 : 1, 5, 11, 55, 121, 605
719 : 1, 719
473 : 1, 11, 43, 473
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,719,473,891, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
719:719
473:11x 43
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 183325597785/(1x121)
LCM = 183325597785/121
LCM = 1515087585
Thus, we can understand that the LCM of 605,719,473,891 is 1515087585.
