Given numbers are 13,61,897

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

The LCM of 13,61,897 is 54717.

Find LCM of 13,61,897 with Prime Factorization

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

13 x 1 x 61 x 69 = 54717

Therefore, the lowest common multiple of 13,61,897 is 54717.

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.

13 x 61 x 897 = 711321

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.

13 : 1, 13

61 : 1, 61

897 : 1, 3, 13, 23, 39, 69, 299, 897

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 13,61,897, is 1.

Now, the common factors can be found like this.

13:13

61:61

897:3x 13x 23

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

13 = 13

Therefore, the value for common factors is 13.

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 = 711321/(1x13)

LCM = 711321/13

LCM = 54717

Thus, we can understand that the LCM of 13,61,897 is 54717.
