Given numbers are 818,409,981

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

The LCM of 818,409,981 is 802458.

Find LCM of 818,409,981 with Prime Factorization

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

409 x 2 x 1 x 981 = 802458

Therefore, the lowest common multiple of 818,409,981 is 802458.

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.

818 x 409 x 981 = 328205322

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.

818 : 1, 2, 409, 818

409 : 1, 409

981 : 1, 3, 9, 109, 327, 981

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,409,981, is 1.

Now, the common factors can be found like this.

818:2x 409

409:409

981:3x 3x 109

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

409 = 409

Therefore, the value for common factors is 409.

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 = 328205322/(1x409)

LCM = 328205322/409

LCM = 802458

Thus, we can understand that the LCM of 818,409,981 is 802458.

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

• LCM of 438, 595, 458
• LCM of 975, 981, 682
