Given numbers are 505,845,845,445
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,845,845,445 is 7595705.
Find LCM of 505,845,845,445 with Prime Factorization
5 | 505, 845, 845, 445 |
13 | 101, 169, 169, 89 |
13 | 101, 13, 13, 89 |
101, 1, 1, 89 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 13 x 101 x 1 x 1 x 89 = 7595705
Therefore, the lowest common multiple of 505,845,845,445 is 7595705.
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.
505 x 845 x 845 x 445 = 160459268125
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.
505 : 1, 5, 101, 505
845 : 1, 5, 13, 65, 169, 845
845 : 1, 5, 13, 65, 169, 845
445 : 1, 5, 89, 445
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,845,845,445, is 5.
Now, the common factors can be found like this.
505:5x 101
845:5x 13x 13
845:5x 13x 13
445:5x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 13x 13 = 4225
Therefore, the value for common factors is 4225.
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 = 160459268125/(5x4225)
LCM = 160459268125/21125
LCM = 7595705
Thus, we can understand that the LCM of 505,845,845,445 is 7595705.
