Given numbers are 312,513,704,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 312,513,704,771 is 1206608832.
Find LCM of 312,513,704,771 with Prime Factorization
| 2 | 312, 513, 704, 771 |
| 2 | 156, 513, 352, 771 |
| 2 | 78, 513, 176, 771 |
| 3 | 39, 513, 88, 771 |
| 13, 171, 88, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 171 x 88 x 257 = 1206608832
Therefore, the lowest common multiple of 312,513,704,771 is 1206608832.
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.
312 x 513 x 704 x 771 = 86875835904
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
513 : 1, 3, 9, 19, 27, 57, 171, 513
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,513,704,771, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
513:3x 3x 3x 19
704:2x 2x 2x 2x 2x 2x 11
771:3x 257
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 86875835904/(1x72)
LCM = 86875835904/72
LCM = 1206608832
Thus, we can understand that the LCM of 312,513,704,771 is 1206608832.
