Given numbers are 731,744,946,491,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,744,946,491,356 is 261429442296.
Find LCM of 731,744,946,491,356 with Prime Factorization
| 2 | 731, 744, 946, 491, 356 |
| 2 | 731, 372, 473, 491, 178 |
| 43 | 731, 186, 473, 491, 89 |
| 17, 186, 11, 491, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 17 x 186 x 11 x 491 x 89 = 261429442296
Therefore, the lowest common multiple of 731,744,946,491,356 is 261429442296.
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.
731 x 744 x 946 x 491 x 356 = 89931728149824
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.
731 : 1, 17, 43, 731
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
946 : 1, 2, 11, 22, 43, 86, 473, 946
491 : 1, 491
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,744,946,491,356, is 1.
Now, the common factors can be found like this.
731:17x 43
744:2x 2x 2x 3x 31
946:2x 11x 43
491:491
356:2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 43 = 344
Therefore, the value for common factors is 344.
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 = 89931728149824/(1x344)
LCM = 89931728149824/344
LCM = 261429442296
Thus, we can understand that the LCM of 731,744,946,491,356 is 261429442296.
