Given numbers are 717,717,221

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

The LCM of 717,717,221 is 158457.

Find LCM of 717,717,221 with Prime Factorization

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

3 x 239 x 1 x 1 x 221 = 158457

Therefore, the lowest common multiple of 717,717,221 is 158457.

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.

717 x 717 x 221 = 113613669

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.

717 : 1, 3, 239, 717

717 : 1, 3, 239, 717

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,717,221, is 1.

Now, the common factors can be found like this.

717:3x 239

717:3x 239

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.

3x 239 = 717

Therefore, the value for common factors is 717.

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 = 113613669/(1x717)

LCM = 113613669/717

LCM = 158457

Thus, we can understand that the LCM of 717,717,221 is 158457.

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

• LCM of 517, 815, 871
• LCM of 349, 880, 240
