Given numbers are 994,815,981,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,815,981,930 is 24636255210.
Find LCM of 994,815,981,930 with Prime Factorization
| 2 | 994, 815, 981, 930 |
| 3 | 497, 815, 981, 465 |
| 5 | 497, 815, 327, 155 |
| 497, 163, 327, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 497 x 163 x 327 x 31 = 24636255210
Therefore, the lowest common multiple of 994,815,981,930 is 24636255210.
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.
994 x 815 x 981 x 930 = 739087656300
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
815 : 1, 5, 163, 815
981 : 1, 3, 9, 109, 327, 981
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,815,981,930, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
815:5x 163
981:3x 3x 109
930:2x 3x 5x 31
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 5 = 30
Therefore, the value for common factors is 30.
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 = 739087656300/(1x30)
LCM = 739087656300/30
LCM = 24636255210
Thus, we can understand that the LCM of 994,815,981,930 is 24636255210.
