Given numbers are 3,618,721,431

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

The LCM of 3,618,721,431 is 1864506.

Find LCM of 3,618,721,431 with Prime Factorization

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

3 x 103 x 1 x 2 x 7 x 431 = 1864506

Therefore, the lowest common multiple of 3,618,721,431 is 1864506.

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.

3 x 618 x 721 x 431 = 576132354

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.

3 : 1, 3

618 : 1, 2, 3, 6, 103, 206, 309, 618

721 : 1, 7, 103, 721

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,618,721,431, is 1.

Now, the common factors can be found like this.

3:3

618:2x 3x 103

721:7x 103

431:431

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

3x 103 = 309

Therefore, the value for common factors is 309.

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 = 576132354/(1x309)

LCM = 576132354/309

LCM = 1864506

Thus, we can understand that the LCM of 3,618,721,431 is 1864506.

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

• LCM of 8, 681, 654, 237
