Given numbers are 688,328,208,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,328,208,966 is 177118032.
Find LCM of 688,328,208,966 with Prime Factorization
| 2 | 688, 328, 208, 966 |
| 2 | 344, 164, 104, 483 |
| 2 | 172, 82, 52, 483 |
| 2 | 86, 41, 26, 483 |
| 43, 41, 13, 483 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 41 x 13 x 483 = 177118032
Therefore, the lowest common multiple of 688,328,208,966 is 177118032.
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.
688 x 328 x 208 x 966 = 45342216192
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
328 : 1, 2, 4, 8, 41, 82, 164, 328
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,328,208,966, is 2.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
328:2x 2x 2x 41
208:2x 2x 2x 2x 13
966:2x 3x 7x 23
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 2x 2x 2x 2 = 128
Therefore, the value for common factors is 128.
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 = 45342216192/(2x128)
LCM = 45342216192/256
LCM = 177118032
Thus, we can understand that the LCM of 688,328,208,966 is 177118032.
