Given numbers are 731,716,790,711
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,716,790,711 is 1860672780.
Find LCM of 731,716,790,711 with Prime Factorization
| 2 | 731, 716, 790, 711 |
| 79 | 731, 358, 395, 711 |
| 731, 358, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 79 x 731 x 358 x 5 x 9 = 1860672780
Therefore, the lowest common multiple of 731,716,790,711 is 1860672780.
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 716 x 790 x 711 = 293986299240
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
716 : 1, 2, 4, 179, 358, 716
790 : 1, 2, 5, 10, 79, 158, 395, 790
711 : 1, 3, 9, 79, 237, 711
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,716,790,711, is 1.
Now, the common factors can be found like this.
731:17x 43
716:2x 2x 179
790:2x 5x 79
711:3x 3x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 79 = 158
Therefore, the value for common factors is 158.
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 = 293986299240/(1x158)
LCM = 293986299240/158
LCM = 1860672780
Thus, we can understand that the LCM of 731,716,790,711 is 1860672780.
