Given numbers are 655,919,133,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,919,133,455 is 1040762905.
Find LCM of 655,919,133,455 with Prime Factorization
| 5 | 655, 919, 133, 455 |
| 7 | 131, 919, 133, 91 |
| 131, 919, 19, 13 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 131 x 919 x 19 x 13 = 1040762905
Therefore, the lowest common multiple of 655,919,133,455 is 1040762905.
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.
655 x 919 x 133 x 455 = 36426701675
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.
655 : 1, 5, 131, 655
919 : 1, 919
133 : 1, 7, 19, 133
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,919,133,455, is 1.
Now, the common factors can be found like this.
655:5x 131
919:919
133:7x 19
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 36426701675/(1x35)
LCM = 36426701675/35
LCM = 1040762905
Thus, we can understand that the LCM of 655,919,133,455 is 1040762905.
