Given numbers are 831,157,642

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

The LCM of 831,157,642 is 27919938.

Find LCM of 831,157,642 with Prime Factorization

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

3 x 277 x 157 x 214 = 27919938

Therefore, the lowest common multiple of 831,157,642 is 27919938.

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.

831 x 157 x 642 = 83759814

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.

831 : 1, 3, 277, 831

157 : 1, 157

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,157,642, is 1.

Now, the common factors can be found like this.

831:3x 277

157:157

642:2x 3x 107

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 = 83759814/(1x3)

LCM = 83759814/3

LCM = 27919938

Thus, we can understand that the LCM of 831,157,642 is 27919938.

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

• LCM of 648, 650, 101
• LCM of 422, 830, 678
