Given numbers are 100,940,845,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,940,845,809 is 642588700.
Find LCM of 100,940,845,809 with Prime Factorization
2 | 100, 940, 845, 809 |
2 | 50, 470, 845, 809 |
5 | 25, 235, 845, 809 |
5, 47, 169, 809 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 47 x 169 x 809 = 642588700
Therefore, the lowest common multiple of 100,940,845,809 is 642588700.
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.
100 x 940 x 845 x 809 = 64258870000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
845 : 1, 5, 13, 65, 169, 845
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,940,845,809, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
940:2x 2x 5x 47
845:5x 13x 13
809:809
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 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 64258870000/(1x100)
LCM = 64258870000/100
LCM = 642588700
Thus, we can understand that the LCM of 100,940,845,809 is 642588700.
