The LCM of 819,412,964,988 is 1545082812.
Find LCM of 819,412,964,988 with Prime Factorization
| 2 | 819, 412, 964, 988 |
| 2 | 819, 206, 482, 494 |
| 13 | 819, 103, 241, 247 |
| 63, 103, 241, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 63 x 103 x 241 x 19 = 1545082812
Therefore, the lowest common multiple of 819,412,964,988 is 1545082812.
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.
819 x 412 x 964 x 988 = 321377224896
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
412 : 1, 2, 4, 103, 206, 412
964 : 1, 2, 4, 241, 482, 964
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,412,964,988, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
412:2x 2x 103
964:2x 2x 241
988:2x 2x 13x 19
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 13 = 208
Therefore, the value for common factors is 208.
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 = 321377224896/(1x208)
LCM = 321377224896/208
LCM = 1545082812
Thus, we can understand that the LCM of 819,412,964,988 is 1545082812.
