Given numbers are 756,464,398,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 756,464,398,400 is 436287600.
Find LCM of 756,464,398,400 with Prime Factorization
| 2 | 756, 464, 398, 400 |
| 2 | 378, 232, 199, 200 |
| 2 | 189, 116, 199, 100 |
| 2 | 189, 58, 199, 50 |
| 189, 29, 199, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 189 x 29 x 199 x 25 = 436287600
Therefore, the lowest common multiple of 756,464,398,400 is 436287600.
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.
756 x 464 x 398 x 400 = 55844812800
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.
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
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
398 : 1, 2, 199, 398
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,464,398,400, is 2.
Now, the common factors can be found like this.
756:2x 2x 3x 3x 3x 7
464:2x 2x 2x 2x 29
398:2x 199
400:2x 2x 2x 2x 5x 5
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 = 55844812800/(2x64)
LCM = 55844812800/128
LCM = 436287600
Thus, we can understand that the LCM of 756,464,398,400 is 436287600.
