Given numbers are 698,180,858,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,180,858,308 is 62882820.
Find LCM of 698,180,858,308 with Prime Factorization
| 2 | 698, 180, 858, 308 |
| 2 | 349, 90, 429, 154 |
| 3 | 349, 45, 429, 77 |
| 11 | 349, 15, 143, 77 |
| 349, 15, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 349 x 15 x 13 x 7 = 62882820
Therefore, the lowest common multiple of 698,180,858,308 is 62882820.
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.
698 x 180 x 858 x 308 = 33202128960
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.
698 : 1, 2, 349, 698
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,180,858,308, is 2.
Now, the common factors can be found like this.
698:2x 349
180:2x 2x 3x 3x 5
858:2x 3x 11x 13
308:2x 2x 7x 11
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 11 = 264
Therefore, the value for common factors is 264.
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 = 33202128960/(2x264)
LCM = 33202128960/528
LCM = 62882820
Thus, we can understand that the LCM of 698,180,858,308 is 62882820.
