Given numbers are 126,747,630,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 126,747,630,796 is 20811420.
Find LCM of 126,747,630,796 with Prime Factorization
| 2 | 126, 747, 630, 796 |
| 3 | 63, 747, 315, 398 |
| 3 | 21, 249, 105, 398 |
| 7 | 7, 83, 35, 398 |
| 1, 83, 5, 398 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 1 x 83 x 5 x 398 = 20811420
Therefore, the lowest common multiple of 126,747,630,796 is 20811420.
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 747 x 630 x 796 = 47200300560
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
747 : 1, 3, 9, 83, 249, 747
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
796 : 1, 2, 4, 199, 398, 796
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,747,630,796, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
747:3x 3x 83
630:2x 3x 3x 5x 7
796:2x 2x 199
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 3x 3x 3x 3x 7 = 2268
Therefore, the value for common factors is 2268.
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 = 47200300560/(1x2268)
LCM = 47200300560/2268
LCM = 20811420
Thus, we can understand that the LCM of 126,747,630,796 is 20811420.
