Given numbers are 605,646,995,273,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,646,995,273,143 is 21232621410.
Find LCM of 605,646,995,273,143 with Prime Factorization
| 5 | 605, 646, 995, 273, 143 |
| 11 | 121, 646, 199, 273, 143 |
| 13 | 11, 646, 199, 273, 13 |
| 11, 646, 199, 21, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 11 x 646 x 199 x 21 x 1 = 21232621410
Therefore, the lowest common multiple of 605,646,995,273,143 is 21232621410.
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 646 x 995 x 273 x 143 = 15181324308150
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
995 : 1, 5, 199, 995
273 : 1, 3, 7, 13, 21, 39, 91, 273
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,646,995,273,143, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
646:2x 17x 19
995:5x 199
273:3x 7x 13
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 13 = 715
Therefore, the value for common factors is 715.
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 = 15181324308150/(1x715)
LCM = 15181324308150/715
LCM = 21232621410
Thus, we can understand that the LCM of 605,646,995,273,143 is 21232621410.
