Given numbers are 815,711,185,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,711,185,814 is 471684510.
Find LCM of 815,711,185,814 with Prime Factorization
| 5 | 815, 711, 185, 814 |
| 37 | 163, 711, 37, 814 |
| 163, 711, 1, 22 |
Multiply the prime numbers at the bottom and the left side.
5 x 37 x 163 x 711 x 1 x 22 = 471684510
Therefore, the lowest common multiple of 815,711,185,814 is 471684510.
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.
815 x 711 x 185 x 814 = 87261634350
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.
815 : 1, 5, 163, 815
711 : 1, 3, 9, 79, 237, 711
185 : 1, 5, 37, 185
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,711,185,814, is 1.
Now, the common factors can be found like this.
815:5x 163
711:3x 3x 79
185:5x 37
814:2x 11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 37 = 185
Therefore, the value for common factors is 185.
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 = 87261634350/(1x185)
LCM = 87261634350/185
LCM = 471684510
Thus, we can understand that the LCM of 815,711,185,814 is 471684510.
