Given numbers are 661,471,661

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

The LCM of 661,471,661 is 311331.

Find LCM of 661,471,661 with Prime Factorization

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

661 x 1 x 471 x 1 = 311331

Therefore, the lowest common multiple of 661,471,661 is 311331.

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.

661 x 471 x 661 = 205789791

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.

661 : 1, 661

471 : 1, 3, 157, 471

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,471,661, is 1.

Now, the common factors can be found like this.

661:661

471:3x 157

661:661

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

661 = 661

Therefore, the value for common factors is 661.

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 = 205789791/(1x661)

LCM = 205789791/661

LCM = 311331

Thus, we can understand that the LCM of 661,471,661 is 311331.

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

• LCM of 229, 394, 706
