Given numbers are 783,788,891,500
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 783,788,891,500 is 2545141500.
Find LCM of 783,788,891,500 with Prime Factorization
| 2 | 783, 788, 891, 500 |
| 2 | 783, 394, 891, 250 |
| 3 | 783, 197, 891, 125 |
| 3 | 261, 197, 297, 125 |
| 3 | 87, 197, 99, 125 |
| 29, 197, 33, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 29 x 197 x 33 x 125 = 2545141500
Therefore, the lowest common multiple of 783,788,891,500 is 2545141500.
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.
783 x 788 x 891 x 500 = 274875282000
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.
783 : 1, 3, 9, 27, 29, 87, 261, 783
788 : 1, 2, 4, 197, 394, 788
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,788,891,500, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
788:2x 2x 197
891:3x 3x 3x 3x 11
500:2x 2x 5x 5x 5
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 274875282000/(1x108)
LCM = 274875282000/108
LCM = 2545141500
Thus, we can understand that the LCM of 783,788,891,500 is 2545141500.
