Given numbers are 789,462,142,497,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,462,142,497,994 is 8626926.
Find LCM of 789,462,142,497,994 with Prime Factorization
| 2 | 789, 462, 142, 497, 994 |
| 3 | 789, 231, 71, 497, 497 |
| 7 | 263, 77, 71, 497, 497 |
| 71 | 263, 11, 71, 71, 71 |
| 263, 11, 1, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 263 x 11 x 1 x 1 x 1 = 8626926
Therefore, the lowest common multiple of 789,462,142,497,994 is 8626926.
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.
789 x 462 x 142 x 497 x 994 = 25571140372008
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.
789 : 1, 3, 263, 789
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
142 : 1, 2, 71, 142
497 : 1, 7, 71, 497
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,462,142,497,994, is 1.
Now, the common factors can be found like this.
789:3x 263
462:2x 3x 7x 11
142:2x 71
497:7x 71
994:2x 7x 71
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 3x 7x 7x 71x 71 = 2964108
Therefore, the value for common factors is 2964108.
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 = 25571140372008/(1x2964108)
LCM = 25571140372008/2964108
LCM = 8626926
Thus, we can understand that the LCM of 789,462,142,497,994 is 8626926.
