Given numbers are 811,247,312,395,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,247,312,395,931 is 93051252840.
Find LCM of 811,247,312,395,931 with Prime Factorization
| 13 | 811, 247, 312, 395, 931 |
| 19 | 811, 19, 24, 395, 931 |
| 811, 1, 24, 395, 49 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 811 x 1 x 24 x 395 x 49 = 93051252840
Therefore, the lowest common multiple of 811,247,312,395,931 is 93051252840.
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.
811 x 247 x 312 x 395 x 931 = 22983659451480
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.
811 : 1, 811
247 : 1, 13, 19, 247
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
395 : 1, 5, 79, 395
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,247,312,395,931, is 1.
Now, the common factors can be found like this.
811:811
247:13x 19
312:2x 2x 2x 3x 13
395:5x 79
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 22983659451480/(1x247)
LCM = 22983659451480/247
LCM = 93051252840
Thus, we can understand that the LCM of 811,247,312,395,931 is 93051252840.
