Given numbers are 478,256,478,83
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,256,478,83 is 5078272.
Find LCM of 478,256,478,83 with Prime Factorization
| 2 | 478, 256, 478, 83 |
| 239 | 239, 128, 239, 83 |
| 1, 128, 1, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 1 x 128 x 1 x 83 = 5078272
Therefore, the lowest common multiple of 478,256,478,83 is 5078272.
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.
478 x 256 x 478 x 83 = 4854828032
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.
478 : 1, 2, 239, 478
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
478 : 1, 2, 239, 478
83 : 1, 83
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,256,478,83, is 1.
Now, the common factors can be found like this.
478:2x 239
256:2x 2x 2x 2x 2x 2x 2x 2
478:2x 239
83:83
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 239 = 956
Therefore, the value for common factors is 956.
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 = 4854828032/(1x956)
LCM = 4854828032/956
LCM = 5078272
Thus, we can understand that the LCM of 478,256,478,83 is 5078272.
