Given numbers are 807,690,845,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,690,845,397 is 12453131730.
Find LCM of 807,690,845,397 with Prime Factorization
3 | 807, 690, 845, 397 |
5 | 269, 230, 845, 397 |
269, 46, 169, 397 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 269 x 46 x 169 x 397 = 12453131730
Therefore, the lowest common multiple of 807,690,845,397 is 12453131730.
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.
807 x 690 x 845 x 397 = 186796975950
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.
807 : 1, 3, 269, 807
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
845 : 1, 5, 13, 65, 169, 845
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,690,845,397, is 1.
Now, the common factors can be found like this.
807:3x 269
690:2x 3x 5x 23
845:5x 13x 13
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 186796975950/(1x15)
LCM = 186796975950/15
LCM = 12453131730
Thus, we can understand that the LCM of 807,690,845,397 is 12453131730.
