Find LCM of 117,465,876,438,961 with Prime Factorization
| 2 | 117, 465, 876, 438, 961 |
| 3 | 117, 465, 438, 219, 961 |
| 31 | 39, 155, 146, 73, 961 |
| 73 | 39, 5, 146, 73, 31 |
| 39, 5, 2, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 31 x 73 x 39 x 5 x 2 x 1 x 31 = 164158020
Therefore, the lowest common multiple of 117,465,876,438,961 is 164158020.
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.
117 x 465 x 876 x 438 x 961 = 20060438360040
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.
117 : 1, 3, 9, 13, 39, 117
465 : 1, 3, 5, 15, 31, 93, 155, 465
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
438 : 1, 2, 3, 6, 73, 146, 219, 438
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,465,876,438,961, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
465:3x 5x 31
876:2x 2x 3x 73
438:2x 3x 73
961:31x 31
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 31x 73 = 122202
Therefore, the value for common factors is 122202.
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 = 20060438360040/(1x122202)
LCM = 20060438360040/122202
LCM = 164158020
Thus, we can understand that the LCM of 117,465,876,438,961 is 164158020.
