Given numbers are 128,275,550,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 128,275,550,451 is 1443200.
Find LCM of 128,275,550,451 with Prime Factorization
| 2 | 128, 275, 550, 451 |
| 5 | 64, 275, 275, 451 |
| 5 | 64, 55, 55, 451 |
| 11 | 64, 11, 11, 451 |
| 64, 1, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 11 x 64 x 1 x 1 x 41 = 1443200
Therefore, the lowest common multiple of 128,275,550,451 is 1443200.
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.
128 x 275 x 550 x 451 = 8731360000
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
275 : 1, 5, 11, 25, 55, 275
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,275,550,451, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
275:5x 5x 11
550:2x 5x 5x 11
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 11x 11 = 6050
Therefore, the value for common factors is 6050.
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 = 8731360000/(1x6050)
LCM = 8731360000/6050
LCM = 1443200
Thus, we can understand that the LCM of 128,275,550,451 is 1443200.
