Given numbers are 220,858,771,512
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,858,771,512 is 282247680.
Find LCM of 220,858,771,512 with Prime Factorization
| 2 | 220, 858, 771, 512 |
| 2 | 110, 429, 771, 256 |
| 3 | 55, 429, 771, 128 |
| 11 | 55, 143, 257, 128 |
| 5, 13, 257, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 5 x 13 x 257 x 128 = 282247680
Therefore, the lowest common multiple of 220,858,771,512 is 282247680.
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.
220 x 858 x 771 x 512 = 74513387520
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
771 : 1, 3, 257, 771
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,858,771,512, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
858:2x 3x 11x 13
771:3x 257
512:2x 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 2x 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 74513387520/(1x264)
LCM = 74513387520/264
LCM = 282247680
Thus, we can understand that the LCM of 220,858,771,512 is 282247680.
