Given numbers are 117,865,221

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

The LCM of 117,865,221 is 1720485.

Find LCM of 117,865,221 with Prime Factorization

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

13 x 9 x 865 x 17 = 1720485

Therefore, the lowest common multiple of 117,865,221 is 1720485.

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.

117 x 865 x 221 = 22366305

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.

117 : 1, 3, 9, 13, 39, 117

865 : 1, 5, 173, 865

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,865,221, is 1.

Now, the common factors can be found like this.

117:3x 3x 13

865:5x 173

221:13x 17

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

13 = 13

Therefore, the value for common factors is 13.

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 = 22366305/(1x13)

LCM = 22366305/13

LCM = 1720485

Thus, we can understand that the LCM of 117,865,221 is 1720485.

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

• LCM of 742, 795, 254
• LCM of 688, 197, 409
