Given numbers are 478,478,869,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,478,869,986 is 204783326.
Find LCM of 478,478,869,986 with Prime Factorization
2 | 478, 478, 869, 986 |
239 | 239, 239, 869, 493 |
1, 1, 869, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 1 x 1 x 869 x 493 = 204783326
Therefore, the lowest common multiple of 478,478,869,986 is 204783326.
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 478 x 869 x 986 = 195772859656
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
478 : 1, 2, 239, 478
869 : 1, 11, 79, 869
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,478,869,986, is 1.
Now, the common factors can be found like this.
478:2x 239
478:2x 239
869:11x 79
986:2x 17x 29
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 = 195772859656/(1x956)
LCM = 195772859656/956
LCM = 204783326
Thus, we can understand that the LCM of 478,478,869,986 is 204783326.
