The LCM of 392,896,980,917 is 4108160.
Find LCM of 392,896,980,917 with Prime Factorization
| 2 | 392, 896, 980, 917 |
| 2 | 196, 448, 490, 917 |
| 2 | 98, 224, 245, 917 |
| 7 | 49, 112, 245, 917 |
| 7 | 7, 16, 35, 131 |
| 1, 16, 5, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 1 x 16 x 5 x 131 = 4108160
Therefore, the lowest common multiple of 392,896,980,917 is 4108160.
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.
392 x 896 x 980 x 917 = 315638149120
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
917 : 1, 7, 131, 917
7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,896,980,917, is 7.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
896:2x 2x 2x 2x 2x 2x 2x 7
980:2x 2x 5x 7x 7
917:7x 131
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 2x 2x 7x 7x 7 = 10976
Therefore, the value for common factors is 10976.
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 = 315638149120/(7x10976)
LCM = 315638149120/76832
LCM = 4108160
Thus, we can understand that the LCM of 392,896,980,917 is 4108160.
