Given numbers are 821,253,187

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

The LCM of 821,253,187 is 3531121.

Find LCM of 821,253,187 with Prime Factorization

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

11 x 821 x 23 x 17 = 3531121

Therefore, the lowest common multiple of 821,253,187 is 3531121.

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.

821 x 253 x 187 = 38842331

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.

821 : 1, 821

253 : 1, 11, 23, 253

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,253,187, is 1.

Now, the common factors can be found like this.

821:821

253:11x 23

187:11x 17

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

11 = 11

Therefore, the value for common factors is 11.

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 = 38842331/(1x11)

LCM = 38842331/11

LCM = 3531121

Thus, we can understand that the LCM of 821,253,187 is 3531121.

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

• LCM of 869, 175, 781
• LCM of 788, 307, 170
