Find LCM of 716,864,126,648 with Prime Factorization
| 2 | 716, 864, 126, 648 |
| 2 | 358, 432, 63, 324 |
| 2 | 179, 216, 63, 162 |
| 3 | 179, 108, 63, 81 |
| 3 | 179, 36, 21, 27 |
| 3 | 179, 12, 7, 9 |
| 179, 4, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 179 x 4 x 7 x 3 = 3247776
Therefore, the lowest common multiple of 716,864,126,648 is 3247776.
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.
716 x 864 x 126 x 648 = 50509412352
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.
716 : 1, 2, 4, 179, 358, 716
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 716,864,126,648, is 2.
Now, the common factors can be found like this.
716:2x 2x 179
864:2x 2x 2x 2x 2x 3x 3x 3
126:2x 3x 3x 7
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3 = 7776
Therefore, the value for common factors is 7776.
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 = 50509412352/(2x7776)
LCM = 50509412352/15552
LCM = 3247776
Thus, we can understand that the LCM of 716,864,126,648 is 3247776.
