Given numbers are 975,705,858,256
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,705,858,256 is 129043200.
Find LCM of 975,705,858,256 with Prime Factorization
| 2 | 975, 705, 858, 256 |
| 3 | 975, 705, 429, 128 |
| 5 | 325, 235, 143, 128 |
| 13 | 65, 47, 143, 128 |
| 5, 47, 11, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 5 x 47 x 11 x 128 = 129043200
Therefore, the lowest common multiple of 975,705,858,256 is 129043200.
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.
975 x 705 x 858 x 256 = 150980544000
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
705 : 1, 3, 5, 15, 47, 141, 235, 705
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,705,858,256, is 1.
Now, the common factors can be found like this.
975:3x 5x 5x 13
705:3x 5x 47
858:2x 3x 11x 13
256:2x 2x 2x 2x 2x 2x 2x 2
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 13 = 1170
Therefore, the value for common factors is 1170.
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 = 150980544000/(1x1170)
LCM = 150980544000/1170
LCM = 129043200
Thus, we can understand that the LCM of 975,705,858,256 is 129043200.
