Given numbers are 897,331,890,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,331,890,542 is 71610999330.
Find LCM of 897,331,890,542 with Prime Factorization
| 2 | 897, 331, 890, 542 |
| 897, 331, 445, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 897 x 331 x 445 x 271 = 71610999330
Therefore, the lowest common multiple of 897,331,890,542 is 71610999330.
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.
897 x 331 x 890 x 542 = 143221998660
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
331 : 1, 331
890 : 1, 2, 5, 10, 89, 178, 445, 890
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,331,890,542, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
331:331
890:2x 5x 89
542:2x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 143221998660/(1x2)
LCM = 143221998660/2
LCM = 71610999330
Thus, we can understand that the LCM of 897,331,890,542 is 71610999330.
