Given numbers are 142,714,756,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,714,756,447 is 135961308.
Find LCM of 142,714,756,447 with Prime Factorization
| 2 | 142, 714, 756, 447 |
| 3 | 71, 357, 378, 447 |
| 7 | 71, 119, 126, 149 |
| 71, 17, 18, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 17 x 18 x 149 = 135961308
Therefore, the lowest common multiple of 142,714,756,447 is 135961308.
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.
142 x 714 x 756 x 447 = 34262249616
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.
142 : 1, 2, 71, 142
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,714,756,447, is 1.
Now, the common factors can be found like this.
142:2x 71
714:2x 3x 7x 17
756:2x 2x 3x 3x 3x 7
447:3x 149
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 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 34262249616/(1x252)
LCM = 34262249616/252
LCM = 135961308
Thus, we can understand that the LCM of 142,714,756,447 is 135961308.
