Find LCM of 784,294,348,634 with Prime Factorization
| 2 | 784, 294, 348, 634 |
| 2 | 392, 147, 174, 317 |
| 3 | 196, 147, 87, 317 |
| 7 | 196, 49, 29, 317 |
| 7 | 28, 7, 29, 317 |
| 4, 1, 29, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 7 x 4 x 1 x 29 x 317 = 21621936
Therefore, the lowest common multiple of 784,294,348,634 is 21621936.
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.
784 x 294 x 348 x 634 = 50854793472
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
634 : 1, 2, 317, 634
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,294,348,634, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
294:2x 3x 7x 7
348:2x 2x 3x 29
634:2x 317
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 7 = 1176
Therefore, the value for common factors is 1176.
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 = 50854793472/(2x1176)
LCM = 50854793472/2352
LCM = 21621936
Thus, we can understand that the LCM of 784,294,348,634 is 21621936.
