Given numbers are 361,779,646,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,779,646,578 is 8554978.
Find LCM of 361,779,646,578 with Prime Factorization
| 2 | 361, 779, 646, 578 |
| 17 | 361, 779, 323, 289 |
| 19 | 361, 779, 19, 17 |
| 1, 41, 19, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 1 x 41 x 19 x 17 = 8554978
Therefore, the lowest common multiple of 361,779,646,578 is 8554978.
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.
361 x 779 x 646 x 578 = 105003799972
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.
361 : 1, 19, 361
779 : 1, 19, 41, 779
646 : 1, 2, 17, 19, 34, 38, 323, 646
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,779,646,578, is 1.
Now, the common factors can be found like this.
361:19x 19
779:19x 41
646:2x 17x 19
578:2x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19x 19 = 12274
Therefore, the value for common factors is 12274.
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 = 105003799972/(1x12274)
LCM = 105003799972/12274
LCM = 8554978
Thus, we can understand that the LCM of 361,779,646,578 is 8554978.
