Given numbers are 153,861,197

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

The LCM of 153,861,197 is 8650467.

Find LCM of 153,861,197 with Prime Factorization

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

3 x 51 x 287 x 197 = 8650467

Therefore, the lowest common multiple of 153,861,197 is 8650467.

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.

153 x 861 x 197 = 25951401

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.

153 : 1, 3, 9, 17, 51, 153

861 : 1, 3, 7, 21, 41, 123, 287, 861

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,861,197, is 1.

Now, the common factors can be found like this.

153:3x 3x 17

861:3x 7x 41

197:197

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

3 = 3

Therefore, the value for common factors is 3.

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 = 25951401/(1x3)

LCM = 25951401/3

LCM = 8650467

Thus, we can understand that the LCM of 153,861,197 is 8650467.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 492, 996, 678
• LCM of 219, 605, 994
• LCM of 582, 529, 324
