Given numbers are 865,55,649

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

The LCM of 865,55,649 is 561385.

Find LCM of 865,55,649 with Prime Factorization

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

5 x 11 x 173 x 1 x 59 = 561385

Therefore, the lowest common multiple of 865,55,649 is 561385.

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.

865 x 55 x 649 = 30876175

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.

865 : 1, 5, 173, 865

55 : 1, 5, 11, 55

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,55,649, is 1.

Now, the common factors can be found like this.

865:5x 173

55:5x 11

649:11x 59

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

5x 11 = 55

Therefore, the value for common factors is 55.

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 = 30876175/(1x55)

LCM = 30876175/55

LCM = 561385

Thus, we can understand that the LCM of 865,55,649 is 561385.

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

• LCM of 133, 79, 819
• LCM of 477, 62, 359
