Find LCM of 691,456,868,207,434 with Prime Factorization
| 2 | 691, 456, 868, 207, 434 |
| 2 | 691, 228, 434, 207, 217 |
| 3 | 691, 114, 217, 207, 217 |
| 7 | 691, 38, 217, 69, 217 |
| 31 | 691, 38, 31, 69, 31 |
| 691, 38, 1, 69, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 691 x 38 x 1 x 69 x 1 = 4717932408
Therefore, the lowest common multiple of 691,456,868,207,434 is 4717932408.
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.
691 x 456 x 868 x 207 x 434 = 24570991980864
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.
691 : 1, 691
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
207 : 1, 3, 9, 23, 69, 207
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,456,868,207,434, is 1.
Now, the common factors can be found like this.
691:691
456:2x 2x 2x 3x 19
868:2x 2x 7x 31
207:3x 3x 23
434:2x 7x 31
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 3x 7x 31 = 5208
Therefore, the value for common factors is 5208.
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 = 24570991980864/(1x5208)
LCM = 24570991980864/5208
LCM = 4717932408
Thus, we can understand that the LCM of 691,456,868,207,434 is 4717932408.
