Find LCM of 763,729,243,899,642 with Prime Factorization
| 3 | 763, 729, 243, 899, 642 |
| 3 | 763, 243, 81, 899, 214 |
| 3 | 763, 27, 81, 899, 214 |
| 3 | 763, 9, 27, 899, 214 |
| 3 | 763, 3, 9, 899, 214 |
| 763, 1, 3, 899, 214 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 763 x 1 x 3 x 899 x 214 = 107010287622
Therefore, the lowest common multiple of 763,729,243,899,642 is 107010287622.
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.
763 x 729 x 243 x 899 x 642 = 78010499676438
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.
763 : 1, 7, 109, 763
729 : 1, 3, 9, 27, 81, 243, 729
243 : 1, 3, 9, 27, 81, 243
899 : 1, 29, 31, 899
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 763,729,243,899,642, is 1.
Now, the common factors can be found like this.
763:7x 109
729:3x 3x 3x 3x 3x 3
243:3x 3x 3x 3x 3
899:29x 31
642:2x 3x 107
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 3x 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 78010499676438/(1x729)
LCM = 78010499676438/729
LCM = 107010287622
Thus, we can understand that the LCM of 763,729,243,899,642 is 107010287622.
