Given numbers are 243,701,918,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 243,701,918,780 is 752916060.
Find LCM of 243,701,918,780 with Prime Factorization
| 2 | 243, 701, 918, 780 |
| 3 | 243, 701, 459, 390 |
| 3 | 81, 701, 153, 130 |
| 3 | 27, 701, 51, 130 |
| 9, 701, 17, 130 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 9 x 701 x 17 x 130 = 752916060
Therefore, the lowest common multiple of 243,701,918,780 is 752916060.
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.
243 x 701 x 918 x 780 = 121972401720
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.
243 : 1, 3, 9, 27, 81, 243
701 : 1, 701
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,701,918,780, is 1.
Now, the common factors can be found like this.
243:3x 3x 3x 3x 3
701:701
918:2x 3x 3x 3x 17
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 3x 3x 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 121972401720/(1x162)
LCM = 121972401720/162
LCM = 752916060
Thus, we can understand that the LCM of 243,701,918,780 is 752916060.
