Given numbers are 721,721,898

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

The LCM of 721,721,898 is 647458.

Find LCM of 721,721,898 with Prime Factorization

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

7 x 103 x 1 x 1 x 898 = 647458

Therefore, the lowest common multiple of 721,721,898 is 647458.

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 721 x 898 = 466817218

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

721 : 1, 7, 103, 721

898 : 1, 2, 449, 898

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,721,898, is 1.

Now, the common factors can be found like this.

721:7x 103

721:7x 103

898:2x 449

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

7x 103 = 721

Therefore, the value for common factors is 721.

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 = 466817218/(1x721)

LCM = 466817218/721

LCM = 647458

Thus, we can understand that the LCM of 721,721,898 is 647458.

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

• LCM of 672, 243, 541
• LCM of 211, 721, 452
