Given numbers are 828,100,270,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 828,100,270,102 is 1055700.
Find LCM of 828,100,270,102 with Prime Factorization
| 2 | 828, 100, 270, 102 |
| 2 | 414, 50, 135, 51 |
| 3 | 207, 25, 135, 51 |
| 3 | 69, 25, 45, 17 |
| 5 | 23, 25, 15, 17 |
| 23, 5, 3, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 23 x 5 x 3 x 17 = 1055700
Therefore, the lowest common multiple of 828,100,270,102 is 1055700.
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.
828 x 100 x 270 x 102 = 2280312000
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
102 : 1, 2, 3, 6, 17, 34, 51, 102
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,100,270,102, is 2.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
100:2x 2x 5x 5
270:2x 3x 3x 3x 5
102:2x 3x 17
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 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 2280312000/(2x1080)
LCM = 2280312000/2160
LCM = 1055700
Thus, we can understand that the LCM of 828,100,270,102 is 1055700.
