Find LCM of 678,175,294,831,347 with Prime Factorization
| 2 | 678, 175, 294, 831, 347 |
| 3 | 339, 175, 147, 831, 347 |
| 7 | 113, 175, 49, 277, 347 |
| 113, 25, 7, 277, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 113 x 25 x 7 x 277 x 347 = 79831635450
Therefore, the lowest common multiple of 678,175,294,831,347 is 79831635450.
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.
678 x 175 x 294 x 831 x 347 = 10058786066700
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
175 : 1, 5, 7, 25, 35, 175
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
831 : 1, 3, 277, 831
347 : 1, 347
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,175,294,831,347, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
175:5x 5x 7
294:2x 3x 7x 7
831:3x 277
347:347
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 10058786066700/(1x126)
LCM = 10058786066700/126
LCM = 79831635450
Thus, we can understand that the LCM of 678,175,294,831,347 is 79831635450.
