Given numbers are 252,876,462,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 252,876,462,428 is 21652092.
Find LCM of 252,876,462,428 with Prime Factorization
| 2 | 252, 876, 462, 428 |
| 2 | 126, 438, 231, 214 |
| 3 | 63, 219, 231, 107 |
| 7 | 21, 73, 77, 107 |
| 3, 73, 11, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 3 x 73 x 11 x 107 = 21652092
Therefore, the lowest common multiple of 252,876,462,428 is 21652092.
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.
252 x 876 x 462 x 428 = 43650617472
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
428 : 1, 2, 4, 107, 214, 428
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,876,462,428, is 2.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
876:2x 2x 3x 73
462:2x 3x 7x 11
428:2x 2x 107
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 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 43650617472/(2x1008)
LCM = 43650617472/2016
LCM = 21652092
Thus, we can understand that the LCM of 252,876,462,428 is 21652092.
