Find LCM of 783,441,491,147,407 with Prime Factorization
| 3 | 783, 441, 491, 147, 407 |
| 3 | 261, 147, 491, 49, 407 |
| 7 | 87, 49, 491, 49, 407 |
| 7 | 87, 7, 491, 7, 407 |
| 87, 1, 491, 1, 407 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 7 x 87 x 1 x 491 x 1 x 407 = 7667146179
Therefore, the lowest common multiple of 783,441,491,147,407 is 7667146179.
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 441 x 491 x 147 x 407 = 10143634394817
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
491 : 1, 491
147 : 1, 3, 7, 21, 49, 147
407 : 1, 11, 37, 407
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 783,441,491,147,407, is 1.
Now, the common factors can be found like this.
783:3x 3x 3x 29
441:3x 3x 7x 7
491:491
147:3x 7x 7
407:11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 7 = 1323
Therefore, the value for common factors is 1323.
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 = 10143634394817/(1x1323)
LCM = 10143634394817/1323
LCM = 7667146179
Thus, we can understand that the LCM of 783,441,491,147,407 is 7667146179.
