Given numbers are 421,297,291

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

The LCM of 421,297,291 is 12128589.

Find LCM of 421,297,291 with Prime Factorization

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

3 x 421 x 99 x 97 = 12128589

Therefore, the lowest common multiple of 421,297,291 is 12128589.

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.

421 x 297 x 291 = 36385767

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.

421 : 1, 421

297 : 1, 3, 9, 11, 27, 33, 99, 297

291 : 1, 3, 97, 291

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,297,291, is 1.

Now, the common factors can be found like this.

421:421

297:3x 3x 3x 11

291:3x 97

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

3 = 3

Therefore, the value for common factors is 3.

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 = 36385767/(1x3)

LCM = 36385767/3

LCM = 12128589

Thus, we can understand that the LCM of 421,297,291 is 12128589.

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

• LCM of 493, 287, 114
• LCM of 834, 834, 688
