Given numbers are 721,251,251

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

The LCM of 721,251,251 is 180971.

Find LCM of 721,251,251 with Prime Factorization

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

251 x 721 x 1 x 1 = 180971

Therefore, the lowest common multiple of 721,251,251 is 180971.

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.

721 x 251 x 251 = 45423721

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.

721 : 1, 7, 103, 721

251 : 1, 251

251 : 1, 251

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,251,251, is 1.

Now, the common factors can be found like this.

721:7x 103

251:251

251:251

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

251 = 251

Therefore, the value for common factors is 251.

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 = 45423721/(1x251)

LCM = 45423721/251

LCM = 180971

Thus, we can understand that the LCM of 721,251,251 is 180971.

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

• LCM of 104, 156, 268
• LCM of 855, 900, 506
