The LCM of 705,865,356,256,801 is 8336551680.
Find LCM of 705,865,356,256,801 with Prime Factorization
| 2 | 705, 865, 356, 256, 801 |
| 2 | 705, 865, 178, 128, 801 |
| 3 | 705, 865, 89, 64, 801 |
| 5 | 235, 865, 89, 64, 267 |
| 89 | 47, 173, 89, 64, 267 |
| 47, 173, 1, 64, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 89 x 47 x 173 x 1 x 64 x 3 = 8336551680
Therefore, the lowest common multiple of 705,865,356,256,801 is 8336551680.
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.
705 x 865 x 356 x 256 x 801 = 44517185971200
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
865 : 1, 5, 173, 865
356 : 1, 2, 4, 89, 178, 356
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,865,356,256,801, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
865:5x 173
356:2x 2x 89
256:2x 2x 2x 2x 2x 2x 2x 2
801:3x 3x 89
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 5x 89 = 5340
Therefore, the value for common factors is 5340.
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 = 44517185971200/(1x5340)
LCM = 44517185971200/5340
LCM = 8336551680
Thus, we can understand that the LCM of 705,865,356,256,801 is 8336551680.
