Given numbers are 1668,8210

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

The LCM of 1668,8210 is 6847140.

Find LCM of 1668,8210 with Prime Factorization

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

2 x 834 x 4105 = 6847140

Therefore, the lowest common multiple of 1668,8210 is 6847140.

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.

1668 x 8210 = 13694280

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.

1668 : 1, 2, 3, 4, 6, 12, 139, 278, 417, 556, 834, 1668

8210 : 1, 2, 5, 10, 821, 1642, 4105, 8210

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1668,8210, is 2.

Now, the common factors can be found like this.

1668:2x 2x 3x 139

8210:2x 5x 821

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

= 1

Therefore, the value for common factors is 1.

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 = 13694280/(2x1)

LCM = 13694280/2

LCM = 6847140

Thus, we can understand that the LCM of 1668,8210 is 6847140.

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

• LCM of 2972, 1984
• LCM of 7493, 3499
