Given numbers are 857,411,720

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

The LCM of 857,411,720 is 84534480.

Find LCM of 857,411,720 with Prime Factorization

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

3 x 857 x 137 x 240 = 84534480

Therefore, the lowest common multiple of 857,411,720 is 84534480.

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.

857 x 411 x 720 = 253603440

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.

857 : 1, 857

411 : 1, 3, 137, 411

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,411,720, is 1.

Now, the common factors can be found like this.

857:857

411:3x 137

720:2x 2x 2x 2x 3x 3x 5

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 = 253603440/(1x3)

LCM = 253603440/3

LCM = 84534480

Thus, we can understand that the LCM of 857,411,720 is 84534480.

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

• LCM of 211, 534, 401
