Given numbers are 21,446,847

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

The LCM of 21,446,847 is 1133286.

Find LCM of 21,446,847 with Prime Factorization

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

7 x 3 x 446 x 121 = 1133286

Therefore, the lowest common multiple of 21,446,847 is 1133286.

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.

21 x 446 x 847 = 7933002

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.

21 : 1, 3, 7, 21

446 : 1, 2, 223, 446

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 21,446,847, is 1.

Now, the common factors can be found like this.

21:3x 7

446:2x 223

847:7x 11x 11

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

7 = 7

Therefore, the value for common factors is 7.

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 = 7933002/(1x7)

LCM = 7933002/7

LCM = 1133286

Thus, we can understand that the LCM of 21,446,847 is 1133286.

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

• LCM of 54, 141, 212
• LCM of 77, 588, 358
