Given numbers are 8440,1678

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

The LCM of 8440,1678 is 7081160.

Find LCM of 8440,1678 with Prime Factorization

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

2 x 4220 x 839 = 7081160

Therefore, the lowest common multiple of 8440,1678 is 7081160.

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.

8440 x 1678 = 14162320

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.

8440 : 1, 2, 4, 5, 8, 10, 20, 40, 211, 422, 844, 1055, 1688, 2110, 4220, 8440

1678 : 1, 2, 839, 1678

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 8440,1678, is 2.

Now, the common factors can be found like this.

8440:2x 2x 2x 5x 211

1678:2x 839

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 = 14162320/(2x1)

LCM = 14162320/2

LCM = 7081160

Thus, we can understand that the LCM of 8440,1678 is 7081160.

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

• LCM of 3192, 6397
• LCM of 9493, 2882
