Given numbers are 671,581,854,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,581,854,422 is 164517122.
Find LCM of 671,581,854,422 with Prime Factorization
| 2 | 671, 581, 854, 422 |
| 7 | 671, 581, 427, 211 |
| 61 | 671, 83, 61, 211 |
| 11, 83, 1, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 61 x 11 x 83 x 1 x 211 = 164517122
Therefore, the lowest common multiple of 671,581,854,422 is 164517122.
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.
671 x 581 x 854 x 422 = 140497622188
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.
671 : 1, 11, 61, 671
581 : 1, 7, 83, 581
854 : 1, 2, 7, 14, 61, 122, 427, 854
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,581,854,422, is 1.
Now, the common factors can be found like this.
671:11x 61
581:7x 83
854:2x 7x 61
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 7x 61 = 854
Therefore, the value for common factors is 854.
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 = 140497622188/(1x854)
LCM = 140497622188/854
LCM = 164517122
Thus, we can understand that the LCM of 671,581,854,422 is 164517122.
