Given numbers are 991,687,357

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

The LCM of 991,687,357 is 81017223.

Find LCM of 991,687,357 with Prime Factorization

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

3 x 991 x 229 x 119 = 81017223

Therefore, the lowest common multiple of 991,687,357 is 81017223.

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.

991 x 687 x 357 = 243051669

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.

991 : 1, 991

687 : 1, 3, 229, 687

357 : 1, 3, 7, 17, 21, 51, 119, 357

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,687,357, is 1.

Now, the common factors can be found like this.

991:991

687:3x 229

357:3x 7x 17

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

3 = 3

Therefore, the value for common factors is 3.

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 = 243051669/(1x3)

LCM = 243051669/3

LCM = 81017223

Thus, we can understand that the LCM of 991,687,357 is 81017223.

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

• LCM of 807, 369, 494
• LCM of 594, 898, 614
