Given numbers are 781,173,908,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,173,908,346 is 122682604.
Find LCM of 781,173,908,346 with Prime Factorization
| 2 | 781, 173, 908, 346 |
| 173 | 781, 173, 454, 173 |
| 781, 1, 454, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 173 x 781 x 1 x 454 x 1 = 122682604
Therefore, the lowest common multiple of 781,173,908,346 is 122682604.
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.
781 x 173 x 908 x 346 = 42448180984
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.
781 : 1, 11, 71, 781
173 : 1, 173
908 : 1, 2, 4, 227, 454, 908
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,173,908,346, is 1.
Now, the common factors can be found like this.
781:11x 71
173:173
908:2x 2x 227
346:2x 173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 173 = 346
Therefore, the value for common factors is 346.
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 = 42448180984/(1x346)
LCM = 42448180984/346
LCM = 122682604
Thus, we can understand that the LCM of 781,173,908,346 is 122682604.
