Given numbers are 18,638,977

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

The LCM of 18,638,977 is 5609934.

Find LCM of 18,638,977 with Prime Factorization

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

2 x 9 x 319 x 977 = 5609934

Therefore, the lowest common multiple of 18,638,977 is 5609934.

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.

18 x 638 x 977 = 11219868

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.

18 : 1, 2, 3, 6, 9, 18

638 : 1, 2, 11, 22, 29, 58, 319, 638

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 18,638,977, is 1.

Now, the common factors can be found like this.

18:2x 3x 3

638:2x 11x 29

977:977

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 = 11219868/(1x2)

LCM = 11219868/2

LCM = 5609934

Thus, we can understand that the LCM of 18,638,977 is 5609934.

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

• LCM of 92, 666, 652
• LCM of 69, 943, 595
