Given numbers are 256,869,957,981,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,869,957,981,746 is 2360671619328.
Find LCM of 256,869,957,981,746 with Prime Factorization
| 2 | 256, 869, 957, 981, 746 |
| 3 | 128, 869, 957, 981, 373 |
| 11 | 128, 869, 319, 327, 373 |
| 128, 79, 29, 327, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 128 x 79 x 29 x 327 x 373 = 2360671619328
Therefore, the lowest common multiple of 256,869,957,981,746 is 2360671619328.
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.
256 x 869 x 957 x 981 x 746 = 155804326875648
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
869 : 1, 11, 79, 869
957 : 1, 3, 11, 29, 33, 87, 319, 957
981 : 1, 3, 9, 109, 327, 981
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,869,957,981,746, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
869:11x 79
957:3x 11x 29
981:3x 3x 109
746:2x 373
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 11 = 66
Therefore, the value for common factors is 66.
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 = 155804326875648/(1x66)
LCM = 155804326875648/66
LCM = 2360671619328
Thus, we can understand that the LCM of 256,869,957,981,746 is 2360671619328.
