Given numbers are 270,488,828,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 270,488,828,780 is 19698120.
Find LCM of 270,488,828,780 with Prime Factorization
| 2 | 270, 488, 828, 780 |
| 2 | 135, 244, 414, 390 |
| 3 | 135, 122, 207, 195 |
| 3 | 45, 122, 69, 65 |
| 5 | 15, 122, 23, 65 |
| 3, 122, 23, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 3 x 122 x 23 x 13 = 19698120
Therefore, the lowest common multiple of 270,488,828,780 is 19698120.
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.
270 x 488 x 828 x 780 = 85095878400
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.
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
488 : 1, 2, 4, 8, 61, 122, 244, 488
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 270,488,828,780, is 2.
Now, the common factors can be found like this.
270:2x 3x 3x 3x 5
488:2x 2x 2x 61
828:2x 2x 3x 3x 23
780:2x 2x 3x 5x 13
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 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 85095878400/(2x2160)
LCM = 85095878400/4320
LCM = 19698120
Thus, we can understand that the LCM of 270,488,828,780 is 19698120.
