Given numbers are 837,648,945,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 837,648,945,705 is 33044760.
Find LCM of 837,648,945,705 with Prime Factorization
| 3 | 837, 648, 945, 705 |
| 3 | 279, 216, 315, 235 |
| 3 | 93, 72, 105, 235 |
| 5 | 31, 24, 35, 235 |
| 31, 24, 7, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 31 x 24 x 7 x 47 = 33044760
Therefore, the lowest common multiple of 837,648,945,705 is 33044760.
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.
837 x 648 x 945 x 705 = 361344450600
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.
837 : 1, 3, 9, 27, 31, 93, 279, 837
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
705 : 1, 3, 5, 15, 47, 141, 235, 705
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 837,648,945,705, is 3.
Now, the common factors can be found like this.
837:3x 3x 3x 31
648:2x 2x 2x 3x 3x 3x 3
945:3x 3x 3x 5x 7
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3x 5 = 3645
Therefore, the value for common factors is 3645.
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 = 361344450600/(3x3645)
LCM = 361344450600/10935
LCM = 33044760
Thus, we can understand that the LCM of 837,648,945,705 is 33044760.
