Given numbers are 103,720,867,676,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 103,720,867,676,441 is 177480379440.
Find LCM of 103,720,867,676,441 with Prime Factorization
| 2 | 103, 720, 867, 676, 441 |
| 2 | 103, 360, 867, 338, 441 |
| 3 | 103, 180, 867, 169, 441 |
| 3 | 103, 60, 289, 169, 147 |
| 103, 20, 289, 169, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 103 x 20 x 289 x 169 x 49 = 177480379440
Therefore, the lowest common multiple of 103,720,867,676,441 is 177480379440.
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.
103 x 720 x 867 x 676 x 441 = 19167880979520
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.
103 : 1, 103
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
867 : 1, 3, 17, 51, 289, 867
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,720,867,676,441, is 1.
Now, the common factors can be found like this.
103:103
720:2x 2x 2x 2x 3x 3x 5
867:3x 17x 17
676:2x 2x 13x 13
441:3x 3x 7x 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 2x 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 19167880979520/(1x108)
LCM = 19167880979520/108
LCM = 177480379440
Thus, we can understand that the LCM of 103,720,867,676,441 is 177480379440.
