Given numbers are 836,947,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,947,648 is 128254104.
Find LCM of 836,947,648 with Prime Factorization
| 2 | 836, 947, 648 |
| 2 | 418, 947, 324 |
| 209, 947, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 209 x 947 x 162 = 128254104
Therefore, the lowest common multiple of 836,947,648 is 128254104.
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.
836 x 947 x 648 = 513016416
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
947 : 1, 947
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,947,648, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
947:947
648:2x 2x 2x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 513016416/(1x4)
LCM = 513016416/4
LCM = 128254104
Thus, we can understand that the LCM of 836,947,648 is 128254104.
