Given numbers are 634,708,381,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,708,381,422 is 6014211492.
Find LCM of 634,708,381,422 with Prime Factorization
| 2 | 634, 708, 381, 422 |
| 3 | 317, 354, 381, 211 |
| 317, 118, 127, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 317 x 118 x 127 x 211 = 6014211492
Therefore, the lowest common multiple of 634,708,381,422 is 6014211492.
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.
634 x 708 x 381 x 422 = 72170537904
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.
634 : 1, 2, 317, 634
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
381 : 1, 3, 127, 381
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,708,381,422, is 1.
Now, the common factors can be found like this.
634:2x 317
708:2x 2x 3x 59
381:3x 127
422:2x 211
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 3 = 12
Therefore, the value for common factors is 12.
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 = 72170537904/(1x12)
LCM = 72170537904/12
LCM = 6014211492
Thus, we can understand that the LCM of 634,708,381,422 is 6014211492.
