Given numbers are 242,784,815,655,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,784,815,655,580 is 293716493840.
Find LCM of 242,784,815,655,580 with Prime Factorization
| 2 | 242, 784, 815, 655, 580 |
| 2 | 121, 392, 815, 655, 290 |
| 5 | 121, 196, 815, 655, 145 |
| 121, 196, 163, 131, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 121 x 196 x 163 x 131 x 29 = 293716493840
Therefore, the lowest common multiple of 242,784,815,655,580 is 293716493840.
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.
242 x 784 x 815 x 655 x 580 = 58743298768000
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.
242 : 1, 2, 11, 22, 121, 242
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
815 : 1, 5, 163, 815
655 : 1, 5, 131, 655
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,784,815,655,580, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
784:2x 2x 2x 2x 7x 7
815:5x 163
655:5x 131
580:2x 2x 5x 29
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 5x 5 = 200
Therefore, the value for common factors is 200.
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 = 58743298768000/(1x200)
LCM = 58743298768000/200
LCM = 293716493840
Thus, we can understand that the LCM of 242,784,815,655,580 is 293716493840.
