Find LCM of 381,245,770,847,770 with Prime Factorization
| 2 | 381, 245, 770, 847, 770 |
| 5 | 381, 245, 385, 847, 385 |
| 7 | 381, 49, 77, 847, 77 |
| 11 | 381, 7, 11, 121, 11 |
| 381, 7, 1, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 11 x 381 x 7 x 1 x 1 x 11 = 22589490
Therefore, the lowest common multiple of 381,245,770,847,770 is 22589490.
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.
381 x 245 x 770 x 847 x 770 = 46876580173500
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.
381 : 1, 3, 127, 381
245 : 1, 5, 7, 35, 49, 245
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
847 : 1, 7, 11, 77, 121, 847
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,245,770,847,770, is 1.
Now, the common factors can be found like this.
381:3x 127
245:5x 7x 7
770:2x 5x 7x 11
847:7x 11x 11
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 7x 7x 11x 11 = 2075150
Therefore, the value for common factors is 2075150.
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 = 46876580173500/(1x2075150)
LCM = 46876580173500/2075150
LCM = 22589490
Thus, we can understand that the LCM of 381,245,770,847,770 is 22589490.
