Given numbers are 347,663,888,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,663,888,678 is 7695080328.
Find LCM of 347,663,888,678 with Prime Factorization
| 2 | 347, 663, 888, 678 |
| 3 | 347, 663, 444, 339 |
| 347, 221, 148, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 347 x 221 x 148 x 113 = 7695080328
Therefore, the lowest common multiple of 347,663,888,678 is 7695080328.
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.
347 x 663 x 888 x 678 = 138511445904
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.
347 : 1, 347
663 : 1, 3, 13, 17, 39, 51, 221, 663
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,663,888,678, is 1.
Now, the common factors can be found like this.
347:347
663:3x 13x 17
888:2x 2x 2x 3x 37
678:2x 3x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 138511445904/(1x18)
LCM = 138511445904/18
LCM = 7695080328
Thus, we can understand that the LCM of 347,663,888,678 is 7695080328.
