Given numbers are 617,371,861

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

The LCM of 617,371,861 is 28155561.

Find LCM of 617,371,861 with Prime Factorization

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

7 x 617 x 53 x 123 = 28155561

Therefore, the lowest common multiple of 617,371,861 is 28155561.

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.

617 x 371 x 861 = 197088927

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.

617 : 1, 617

371 : 1, 7, 53, 371

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,371,861, is 1.

Now, the common factors can be found like this.

617:617

371:7x 53

861:3x 7x 41

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

7 = 7

Therefore, the value for common factors is 7.

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 = 197088927/(1x7)

LCM = 197088927/7

LCM = 28155561

Thus, we can understand that the LCM of 617,371,861 is 28155561.

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

• LCM of 816, 263, 976
• LCM of 281, 773, 323
