Find LCM of 787,702,208,336 with Prime Factorization
| 2 | 787, 702, 208, 336 |
| 2 | 787, 351, 104, 168 |
| 2 | 787, 351, 52, 84 |
| 2 | 787, 351, 26, 42 |
| 3 | 787, 351, 13, 21 |
| 13 | 787, 117, 13, 7 |
| 787, 9, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 787 x 9 x 1 x 7 = 30938544
Therefore, the lowest common multiple of 787,702,208,336 is 30938544.
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.
787 x 702 x 208 x 336 = 38611302912
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.
787 : 1, 787
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,702,208,336, is 1.
Now, the common factors can be found like this.
787:787
702:2x 3x 3x 3x 13
208:2x 2x 2x 2x 13
336:2x 2x 2x 2x 3x 7
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 13 = 1248
Therefore, the value for common factors is 1248.
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 = 38611302912/(1x1248)
LCM = 38611302912/1248
LCM = 30938544
Thus, we can understand that the LCM of 787,702,208,336 is 30938544.
