Given numbers are 731,350,815,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,350,815,956 is 19934296900.
Find LCM of 731,350,815,956 with Prime Factorization
| 2 | 731, 350, 815, 956 |
| 5 | 731, 175, 815, 478 |
| 731, 35, 163, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 731 x 35 x 163 x 478 = 19934296900
Therefore, the lowest common multiple of 731,350,815,956 is 19934296900.
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 350 x 815 x 956 = 199342969000
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
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
815 : 1, 5, 163, 815
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,350,815,956, is 1.
Now, the common factors can be found like this.
731:17x 43
350:2x 5x 5x 7
815:5x 163
956:2x 2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 199342969000/(1x10)
LCM = 199342969000/10
LCM = 19934296900
Thus, we can understand that the LCM of 731,350,815,956 is 19934296900.
