Given numbers are 319,845,906,620,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,845,906,620,909 is 4587857368380.
Find LCM of 319,845,906,620,909 with Prime Factorization
| 2 | 319, 845, 906, 620, 909 |
| 3 | 319, 845, 453, 310, 909 |
| 5 | 319, 845, 151, 310, 303 |
| 319, 169, 151, 62, 303 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 319 x 169 x 151 x 62 x 303 = 4587857368380
Therefore, the lowest common multiple of 319,845,906,620,909 is 4587857368380.
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.
319 x 845 x 906 x 620 x 909 = 137635721051400
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.
319 : 1, 11, 29, 319
845 : 1, 5, 13, 65, 169, 845
906 : 1, 2, 3, 6, 151, 302, 453, 906
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,845,906,620,909, is 1.
Now, the common factors can be found like this.
319:11x 29
845:5x 13x 13
906:2x 3x 151
620:2x 2x 5x 31
909:3x 3x 101
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 5 = 30
Therefore, the value for common factors is 30.
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 = 137635721051400/(1x30)
LCM = 137635721051400/30
LCM = 4587857368380
Thus, we can understand that the LCM of 319,845,906,620,909 is 4587857368380.
