Given numbers are 897,985,993,987,247

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 897,985,993,987,247 is 1828126172145.

Find LCM of 897,985,993,987,247 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 13 x 23 x 985 x 331 x 329 x 19 = 1828126172145

Therefore, the lowest common multiple of 897,985,993,987,247 is 1828126172145.

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 985 x 993 x 987 x 247 = 213890762140965

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

985 : 1, 5, 197, 985

993 : 1, 3, 331, 993

987 : 1, 3, 7, 21, 47, 141, 329, 987

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,985,993,987,247, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

985:5x 197

993:3x 331

987:3x 7x 47

247:13x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3x 13 = 117

Therefore, the value for common factors is 117.

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 = 213890762140965/(1x117)

LCM = 213890762140965/117

LCM = 1828126172145

Thus, we can understand that the LCM of 897,985,993,987,247 is 1828126172145.
