Given numbers are 687,142,229

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

The LCM of 687,142,229 is 97554.

Find LCM of 687,142,229 with Prime Factorization

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

229 x 3 x 142 x 1 = 97554

Therefore, the lowest common multiple of 687,142,229 is 97554.

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.

687 x 142 x 229 = 22339866

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.

687 : 1, 3, 229, 687

142 : 1, 2, 71, 142

229 : 1, 229

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,142,229, is 1.

Now, the common factors can be found like this.

687:3x 229

142:2x 71

229:229

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

229 = 229

Therefore, the value for common factors is 229.

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 = 22339866/(1x229)

LCM = 22339866/229

LCM = 97554

Thus, we can understand that the LCM of 687,142,229 is 97554.

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

• LCM of 282, 544, 641
