Given numbers are 954,691,180,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 954,691,180,945 is 138434940.
Find LCM of 954,691,180,945 with Prime Factorization
| 2 | 954, 691, 180, 945 |
| 3 | 477, 691, 90, 945 |
| 3 | 159, 691, 30, 315 |
| 5 | 53, 691, 10, 105 |
| 53, 691, 2, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 53 x 691 x 2 x 21 = 138434940
Therefore, the lowest common multiple of 954,691,180,945 is 138434940.
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.
954 x 691 x 180 x 945 = 112132301400
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.
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
691 : 1, 691
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 954,691,180,945, is 1.
Now, the common factors can be found like this.
954:2x 3x 3x 53
691:691
180:2x 2x 3x 3x 5
945:3x 3x 3x 5x 7
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 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 112132301400/(1x810)
LCM = 112132301400/810
LCM = 138434940
Thus, we can understand that the LCM of 954,691,180,945 is 138434940.
