Given numbers are 386,721,554

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

The LCM of 386,721,554 is 77090762.

Find LCM of 386,721,554 with Prime Factorization

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

2 x 193 x 721 x 277 = 77090762

Therefore, the lowest common multiple of 386,721,554 is 77090762.

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.

386 x 721 x 554 = 154181524

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.

386 : 1, 2, 193, 386

721 : 1, 7, 103, 721

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 386,721,554, is 1.

Now, the common factors can be found like this.

386:2x 193

721:7x 103

554:2x 277

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 = 154181524/(1x2)

LCM = 154181524/2

LCM = 77090762

Thus, we can understand that the LCM of 386,721,554 is 77090762.

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

• LCM of 520, 290, 554
