Given numbers are 328,478,821

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

The LCM of 328,478,821 is 64359832.

Find LCM of 328,478,821 with Prime Factorization

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

2 x 164 x 239 x 821 = 64359832

Therefore, the lowest common multiple of 328,478,821 is 64359832.

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.

328 x 478 x 821 = 128719664

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.

328 : 1, 2, 4, 8, 41, 82, 164, 328

478 : 1, 2, 239, 478

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,478,821, is 1.

Now, the common factors can be found like this.

328:2x 2x 2x 41

478:2x 239

821:821

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 = 128719664/(1x2)

LCM = 128719664/2

LCM = 64359832

Thus, we can understand that the LCM of 328,478,821 is 64359832.

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

• LCM of 424, 155, 544
• LCM of 276, 157, 108
