Given numbers are 126,270,992,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,270,992,668 is 156552480.
Find LCM of 126,270,992,668 with Prime Factorization
| 2 | 126, 270, 992, 668 |
| 2 | 63, 135, 496, 334 |
| 3 | 63, 135, 248, 167 |
| 3 | 21, 45, 248, 167 |
| 7, 15, 248, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 15 x 248 x 167 = 156552480
Therefore, the lowest common multiple of 126,270,992,668 is 156552480.
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.
126 x 270 x 992 x 668 = 22543557120
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
668 : 1, 2, 4, 167, 334, 668
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,270,992,668, is 2.
Now, the common factors can be found like this.
126:2x 3x 3x 7
270:2x 3x 3x 3x 5
992:2x 2x 2x 2x 2x 31
668:2x 2x 167
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 = 22543557120/(2x72)
LCM = 22543557120/144
LCM = 156552480
Thus, we can understand that the LCM of 126,270,992,668 is 156552480.
