Find LCM of 829,504,715,648,644 with Prime Factorization
| 2 | 829, 504, 715, 648, 644 |
| 2 | 829, 252, 715, 324, 322 |
| 2 | 829, 126, 715, 162, 161 |
| 3 | 829, 63, 715, 81, 161 |
| 3 | 829, 21, 715, 27, 161 |
| 7 | 829, 7, 715, 9, 161 |
| 829, 1, 715, 9, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 7 x 829 x 1 x 715 x 9 x 23 = 61838857080
Therefore, the lowest common multiple of 829,504,715,648,644 is 61838857080.
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.
829 x 504 x 715 x 648 x 644 = 124667135873280
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.
829 : 1, 829
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
715 : 1, 5, 11, 13, 55, 65, 143, 715
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 829,504,715,648,644, is 1.
Now, the common factors can be found like this.
829:829
504:2x 2x 2x 3x 3x 7
715:5x 11x 13
648:2x 2x 2x 3x 3x 3x 3
644:2x 2x 7x 23
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 2x 2x 3x 3x 7 = 2016
Therefore, the value for common factors is 2016.
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 = 124667135873280/(1x2016)
LCM = 124667135873280/2016
LCM = 61838857080
Thus, we can understand that the LCM of 829,504,715,648,644 is 61838857080.
