Given numbers are 251,800,656,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,800,656,756 is 1555999200.
Find LCM of 251,800,656,756 with Prime Factorization
| 2 | 251, 800, 656, 756 |
| 2 | 251, 400, 328, 378 |
| 2 | 251, 200, 164, 189 |
| 2 | 251, 100, 82, 189 |
| 251, 50, 41, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 251 x 50 x 41 x 189 = 1555999200
Therefore, the lowest common multiple of 251,800,656,756 is 1555999200.
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.
251 x 800 x 656 x 756 = 99583948800
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.
251 : 1, 251
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,800,656,756, is 1.
Now, the common factors can be found like this.
251:251
800:2x 2x 2x 2x 2x 5x 5
656:2x 2x 2x 2x 41
756:2x 2x 3x 3x 3x 7
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 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 99583948800/(1x64)
LCM = 99583948800/64
LCM = 1555999200
Thus, we can understand that the LCM of 251,800,656,756 is 1555999200.
