Given numbers are 821,262,668

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

The LCM of 821,262,668 is 71844068.

Find LCM of 821,262,668 with Prime Factorization

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

2 x 821 x 131 x 334 = 71844068

Therefore, the lowest common multiple of 821,262,668 is 71844068.

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.

821 x 262 x 668 = 143688136

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.

821 : 1, 821

262 : 1, 2, 131, 262

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,262,668, is 1.

Now, the common factors can be found like this.

821:821

262:2x 131

668:2x 2x 167

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 = 143688136/(1x2)

LCM = 143688136/2

LCM = 71844068

Thus, we can understand that the LCM of 821,262,668 is 71844068.

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

• LCM of 587, 218, 325
