Given numbers are 409,578,634

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

The LCM of 409,578,634 is 74939434.

Find LCM of 409,578,634 with Prime Factorization

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

2 x 409 x 289 x 317 = 74939434

Therefore, the lowest common multiple of 409,578,634 is 74939434.

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.

409 x 578 x 634 = 149878868

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.

409 : 1, 409

578 : 1, 2, 17, 34, 289, 578

634 : 1, 2, 317, 634

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,578,634, is 1.

Now, the common factors can be found like this.

409:409

578:2x 17x 17

634:2x 317

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 = 149878868/(1x2)

LCM = 149878868/2

LCM = 74939434

Thus, we can understand that the LCM of 409,578,634 is 74939434.

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

• LCM of 664, 761, 609
