The LCM of 994,923,780,159 is 20545980.
Find LCM of 994,923,780,159 with Prime Factorization
| 2 | 994, 923, 780, 159 |
| 3 | 497, 923, 390, 159 |
| 13 | 497, 923, 130, 53 |
| 71 | 497, 71, 10, 53 |
| 7, 1, 10, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 71 x 7 x 1 x 10 x 53 = 20545980
Therefore, the lowest common multiple of 994,923,780,159 is 20545980.
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 923 x 780 x 159 = 113783637240
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
923 : 1, 13, 71, 923
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
159 : 1, 3, 53, 159
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,923,780,159, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
923:13x 71
780:2x 2x 3x 5x 13
159:3x 53
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 13x 71 = 5538
Therefore, the value for common factors is 5538.
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 = 113783637240/(1x5538)
LCM = 113783637240/5538
LCM = 20545980
Thus, we can understand that the LCM of 994,923,780,159 is 20545980.
