Given numbers are 387,401,817

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

The LCM of 387,401,817 is 2948553.

Find LCM of 387,401,817 with Prime Factorization

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

43 x 9 x 401 x 19 = 2948553

Therefore, the lowest common multiple of 387,401,817 is 2948553.

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.

387 x 401 x 817 = 126787779

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.

387 : 1, 3, 9, 43, 129, 387

401 : 1, 401

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,401,817, is 1.

Now, the common factors can be found like this.

387:3x 3x 43

401:401

817:19x 43

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

43 = 43

Therefore, the value for common factors is 43.

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 = 126787779/(1x43)

LCM = 126787779/43

LCM = 2948553

Thus, we can understand that the LCM of 387,401,817 is 2948553.

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

• LCM of 816, 703, 927
• LCM of 864, 469, 544
