Given numbers are 485,690,897,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 485,690,897,991 is 862259190.
Find LCM of 485,690,897,991 with Prime Factorization
3 | 485, 690, 897, 991 |
5 | 485, 230, 299, 991 |
23 | 97, 46, 299, 991 |
97, 2, 13, 991 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 97 x 2 x 13 x 991 = 862259190
Therefore, the lowest common multiple of 485,690,897,991 is 862259190.
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.
485 x 690 x 897 x 991 = 297479420550
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.
485 : 1, 5, 97, 485
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
897 : 1, 3, 13, 23, 39, 69, 299, 897
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,690,897,991, is 1.
Now, the common factors can be found like this.
485:5x 97
690:2x 3x 5x 23
897:3x 13x 23
991:991
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 297479420550/(1x345)
LCM = 297479420550/345
LCM = 862259190
Thus, we can understand that the LCM of 485,690,897,991 is 862259190.
